Stayed here for one night with a number of colleagues and used points for the stay. I'm not thrilled with what I got for my points but it was convenient to be with the group. The hotel is appointed like a typical flagship Marriott so it was a reasonably nice room to stay in but there was nothing that really stood out. There was renovation in progress for the porte cochere that complicated check-in but the rest of the lobby was fine. The property is showing a bit of age and while the room was reasonably up-to-date and well maintained, there were a couple of things that tweaked me a bit.
The bath/shower is showing it's age and the water temp moved around on me, also, there was no fan in the bathroom. The bed was comfortable and they did provide my requested foam pillows instead of the way too mushy down. The fridge in the room was really abrupt when it came on, it actually woke me in the night. Internet service was $4.95 per 24 hours - I still don't understand why it's free at lower end properties but charged for at premium properties. The desk lamp in the room was flickering and the bulb was snapping and popping like it was arcing and ready to fail.
From a service standpoint, the staff was quite friendly and helpful and appeared to be genuinely enthusiastic about my being there. I didn't speak to the concierge, but Sam helped out our group with a last minute restaurant reservation nearby and he arranged for cab transportation for 14 people so that was a nice bonus. Bar service in the lobby bar was good and the free wine tasting was a nice touch. As is typical, the breakfast options at the coffee bar were pricey but adequate, I did not eat at the restaurant or in the bar so I cannot speak to the food.
It was raining cats and dogs pretty much throughout our stay so the spread out hotel with limited entrances to parking was a bit of a drag. Overall, my stay was okay but I really don't think I got the value of 30,000 rewards points for 1 night's stay.

just back from 2 nights at the hotel, it was raining about the whole time we were there but we live in las vegas so we enjoy the rain when we get it. our room was off the street and facing the garden so it was quiet. windows open and we loved listening to the rain all night. room was spacious and clean. the wine tasting at 5 is just that, it is not a happy hour or complimentary wine. it's a winery there giving you a couple of ounces trying to sell wine. Dave, the bartender is great. he's a local and is very knowledgeable about the region and the restaurants. he sent us to Il Posto and you should go there too! (very close to the marriott) concierge was very nice and helpful. we were there at a slow time, maybe they have more than one concierge during busy times but it was a wait to visit w/ her. the free shuttle was sort of a weird hassle. we used it and it was nice to be able to drink and not drive but is seemed oddly unorganized. the spa was a great experience, only because of the staff. the spa itself is a little worn and in the ladies side the steam room never got hot. BUT, Eva and Delphina the therapists each gave my husband and i one of the best massages either of us has ever had. REALLY, really sublime. And Britanny at the front desk was super friendly and helpful.

I am a huge fan of Marriott, but the Napa Valley Marriott is definitely below-average in many respects. The hotel feels worn and in need of upgrades. The fitness center was lacking and the place feels much more like a Courtyard or Residence level hotel.

When we were there in November 2012, they were giving the entrance a facelift but it didn't appear they were making any substantive improvements to the property.

I would stay here again only if I needed the nights to keep my Gold status - which is why I stayed here this time. It's a shame, because the area really could use a nice hotel by Marriott.

Picked this one on PriceLine.com...because of the name, mostly. A bit pricey, but the Marriott name and reputation made this a second thought. The night previous was in the Burlingame Hyatt on Thanksgiving Day.

Arrived in Napa, CA the next morning, locating the property and checking in early afternoon. PriceLine had this one at "4 Stars". The entrance was under construction and the workers were sawing and beeping their way through the day. We drove around the 'danger' tape and parked close to our room, second floor facing the expressway, and trudged up the stairs.

The room was 'clean', but that's about all I can say for it. All of the cleanliness one would expect in a consistently maintained property. But the "...This is living, this is MARRIOTT" slogan from the past was not what I was experiencing. The room was average...at best. The non-skid mat on the bottom of the tub/shower appeared and disappeared twice in the three day visit. Hmmmm!

The noise from the construction ended abruptly at 5 PM and we now had to contend with the din from the expressway. Turned on the A/C. The fan was just slightly below the interior noise level of the AirTran jet we had arrived in the day before. However, it did make the traffic noise less noticeable.

Breakfast in the combination lounge/dining area was less than remarkable. "Sit where you like," shouted the waitress as we were searching for a table for two. None which were vacant was clean so we chose a 'hi-boy' table in the center of the room...and sat there for ten minutes, without recognition, set-ups or offer for coffee, while the wait staff was tending to the sparse number of customers around us.

Finally, my wife spoke up loud enough to attract the attention of a busboy who, in turn, motioned to a wait staff person who came over and asked what we wanted. From this point on we were given menus, offered coffee and our order taken. We noted that a nearby group which had come in just before us was lacking attention as well.

As we finished the meal, a woman in a pant-suit and carrying a walkie-talkie stopped and asked about the service. I readily offered that it was a "C" and no more. Gave a short synopsis of our experience so far. She motioned to the server that she "...would take care of the bill." I declined the offer since it was a Holiday and I knew the staff was very pressed in their service. This seemed to take the lady by surprise. However, the diminished tip was explanation enough.

We did not eat in the dinning room/lounge area other than this one time.

The one BRIGHT SPOT of this "4-Star" property was the availability of a "Courtesy Car" 24/7. We used it twice and found it's availability to be convenient and prompt. Since it was the Thanksgiving Day Holiday weekend, we did tip the driver accordingly well.

The property is well-kept and the grounds are well groomed. An herb and vegetable garden is located at the edge of the parking lot. However, the construction equipment and dumpster placement all but hid what could have been a good photo-opportunity.

The Napa Hilton Gardens Inn was next door...should have considered it.

The Napa Valley Marriott Hotel and Spa is a good location for conferences and for folks who are using it as a 'base' from which to visit local wineries, take day tours and/or rendezvous with friends and other associates. There was never a mention of a "spa"...for our use.

A pretentious wine 'tasting' sponsored by a local winery was accompanied by an art 'auction' in the lobby of the hotel. While this seemed to attract a number of folks interested in free wine...the presentation was less than impressive.

For the same price we paid and possibly less, there are several properties in the Downtown Napa area in which you could enjoy a much warmer, personal experience.
