We stayed here for 4 days of our honeymoon.

The Pros:
--its secluded. You get a villa to yourself, so you don't have to deal with noises, etc. We spent many evenings relaxing on the hammock by ourselves.
--the food rules!!! The on-site restaurant is absolutely fabulous. We are from Chicago and I would say it rivals any of the good Chicago restaurants -- Trotters, Alinea, Moto, etc. -- both in quality of ingredient and in innovative preparation and presentation. We had plans galore to try out other area restaurants and just didn't find the need to do so.
--the beach is very close and secluded.
--the accomodations are gorgeous. This is the best bed we slept on during our honeymoon; the sheets and other bedding was very luxurious.
--the spa and yoga classes were great (albeit slightly overpriced compared to the rest of the places we stayed in costa rica).
--we took a surf lesson from one of the instructors on-site and it was great! Highly recommended.
--As a result of being secluded, this place is very hard to get to. We opted to drive from the volcano, and it took about 7 hours -- 3 hours to get to the ferry, 2 hours to get across the ferry, and another 2 hours on the other side (an hour of which were on completely dirty roads). You must have a 4 x 4 and you must do this in the daylight. A GPS is also recommended.

The Cons:
--If you, like me, are hesitant about bugs, lizards, etc., this is a hard place for you to stay. The villa is open air. This means that your bathroom doesn't have a ceiling or walls. While you are peeing or washing your hair, there might be a large lizard staring at you from a tree branch above. My husband loved this; it took me a while to get over my initial squeamishness (looking back, a few months later, it's all fine -- but if you're expecting the Four Season, well, this is just *different*).
--the beach in front of the hotel is pretty rocky and hard to swim or snorkel in - you have to walk a bit down the beach to find a good area for swimming, laying out, etc. I don't know how relevant this is -- we enjoyed our walks on the beach almost as much as laying out or swimming.
--we had one issue where the price advertised for a private yoga session was less than what we were charged. My husband was upset about it at the time, but overall, that's not a huge deal. Just be sure to clarify whether prices have changed since the details were published.

All in all? One of the most memorable experiences of our honeymoon.

I was looking for a relaxing place where I wouldn't be bothered by anyone... The Florblanca delivered! The villas were truly secluded and incredible. The hotel staff was very friendly and made each of my requests happen.
Positives: Amazing sunsets on the beach attached to Florblanca, friendly and accommodating staff, beautiful resort grounds, great pool area, large open villas.
Negatives: Shouldn't count on having internet or cell phone access (but you're on vacation, why would you need it?), since the villas are open you have to expect that you might run across some bugs or animals. I don't mind those things, but I know some people do.
I was there in January and the weather was perfect. I plan on making another trip back sometime!

My wife and I just spent 5 fantastic days at Flor Blanca. Our room, a
1 bdrm garden view, was amazing. Much larger than our NY apartment, very quiet and beautifully appointed with air conditioning and ample lighting in the bedroom, an incredible outdoor shower/bath, and a huge open-air living room. We had the opportunity to switch to an ocean view room but liked the garden view so much that we stayed. FYI it was very quiet but may have been different if we'd had a room further back near the road/parking area.

We found the staff to be professional, courteous, friendly and responsive. The concierge team was very helpful in scheduling everything from our return to San Jose to various activities in a timely and efficient manner, the food and drink service was excellent as well. I've read the reviews complaining about the service and perhaps they forgot they were at a beach resort where everything is supposed to be a bit more relaxed?

Activities: There is a terrific yoga studio that overlooks the beach and the instructor, Nancy, was terrific. The classes are as challenging as you need them to be. Surfing lessons were great and we'd definitely recommend the afternoon/sunset horseback riding at hacienda del arroyo about 15 minutes up the road. Fantastic views, great guides and very healthy horses. Snorkeling at low tide at Playa Sueco was great, Snorkeling off the beaches here is a little strange b/c it's done in tide pools where you're rarely in more than 5 ft of water. The visability isn't great and it feels a bit silly but there are some very cool things to see.

Overall, the best activities here are relaxing, enjoying the beach, having drinks at sunset taking in the amazing views, etc.

Getting there--we flew to Tambor and rented a car there. The drive to Flor Blanca was about 45 min. The Budget rental folks were very helpful. They picked us up at the airport and the car was clean and ready. In driving the rough roads in the Nicoya, a stabilization bar near the rear axle broke but they replaced the car (picking up the old and dropping off the new) at our hotel within an hour or two of notice. Incredible service. Driving the roads around here is a lot of fun and they're generally better than the Osa peninsula. If you get a chance to drive the road from Mal Pais over to Cabuya, do it if you have 4x4. It is absolutely the roughest road we've ever driven
(in a bad rain it'd be impassible) but the scenery is stunnning.
Worth it if you're confident in your vehicle.

Montezuma: We didn't think much of the waterfalls near Montezuma, but there are fantastic beaches and swimming opportunities on the way
to the falls about 5km south of town (about 40 minute hike beyond
yling yling resort).

Florblanca was recommended by a close friend who spent her honeymoon there a few years ago. I was a little nervous, having read a recent review here that was mediocre, but booked it on my friend's strong recommendation.

I couldn't be happier. First of all, the staff was incredibly helpful in arranging flights from San Jose to Tambor, and then ground transportation from there - seamless.

The villas are huge, apparently recently remodeled to have outdoor baths and very modern. We had some industrious termites trying to build something in ours, but they weren't a problem and we alerted the staff who promptly took care of them. But what really blew me away was the food - I have no idea how they managed to get a NYC caliber chef down there - but the menu looked like something out of a restaurant here in the city.

The front office was particularly helpful in setting up activities. I'd recommend the canopy tour (ziplining around the forest, and swimming in waterfalls) as well as the horseback riding on the beach. The beach and scenery are top notch.

I don't have any real complaints. The only thing I'd say is that you get what you pay for -- Florblanca is not cheap. At all. But it was definitely worth it. I'll be going back again.
