I have been traveling on business and this Hotel Sierra was my second stop during my trip. The staff is so nice and the service is impeccable. The hotel makes sure that they have provided everything you will need during your stay. My one bedroom suite had a full kitchen with a sink, full size fridge, microwave, and stove. Its a great place for anyone considering a few short days or extended stay on long projects. When a Hotel Sierra is available, I will be sure to book there.

We Will Be Back!!!
We stayed here by chance because our booked hotel - Days Inn, Parsipanny was rubbish.
We were on a tour of New England and the East Coast and had stayed in 6 other hotels: Marriot Courtyard, La Quinta and Springhill Suite by Marriot before Sierra Suite. Sierra Suite was the best place to stay with kids or without, especially with the provision of home comfort it provided!! The hotel smelled fresh and clean, just like the top-end ones. There were other complimentaries provided that we didn't get to use - evening Happy Hours for guest, basket ball court BBQ, etc.
The check in staff were very helpful, friendly and nice--Michael was outstanding. We will definitely stay at Sierra in which ever State they operate!!!

I stayed at the Sierra Suites for 1 night to attend a wedding in Parsippany. I was shocked to find everything you could imagine in my room. The bed was very comfortable and the room was spacious. There was a kitchen with a sink, refrigerator, dishwasher, stove, dishes, dishtowels, etc. The price they gave us for the wedding party was also terrific at $90 per night. They had free shuttle service to and from the wedding venue which was very convenient, especially if you planned to drink. I highly recommend this hotel for any weddings in the Parsippany area.

I'm writing this review from my room at Sierra Suites. (A single bedroom suite)
Last week I stayed at Staybridge Suites, so this review compares the 2 properties.

I travel on business and prefer extended stay suite hotels.
Both Sierra and Staybridge are ranked #1 & #2 in Tripadvisor at time of this writing and their "top of ranking" for Parsippany is well deserved.

Either of these properties would be a good choice, so how to choose?

ROOM: Sierra is slightly better on room abience (pleasing cozy feeling) and amenities. (cotton bath robe and nice soaps,shampoos). To improve: Sierra water pressure for shower is weak to moderate, and all the main doors to the rooms have a strong (not well adjusted) spring, so slamming of doors is heard and felt.

Both properties are very new, clean and well maintained.

Both properties have comfortable beds and nice linens. The climate control in Sierra is a bit better, but I don't like either system, (Sierra's or Staybridge's) as the control is located in the main room, so it seems the bedroom can go to a different temperature if you close the BR door.

INTERNET ACCESS: Sierra is wireless. Staybridge is wired or wireless in the room and wireless everywhere else.

BREAKFAST and EVENING SNACK: Sierra provides just OK food. Staybridge is far superior. Staybridge evening meal can almost be called a real dinner. Also, at Staybridge, they have an "always" open feel where you can get coffee, tea, soda for free 24/7.

GREAT ROOM: Sierra's is moderate in size, whereas Staybridge is very large with high ceilngs. Staybridge also has a nice library/sitting room + a good business center with 3 computers.

GYM: Sierra has the best gym I've ever seen in a Suites hotel at this price range (see my video) On the other hand, Staybridge is very small (like I typically see)

POOL: Sierra is outdoors, is a nice size and feels a bit resort like, whereas Staybridge is smaller and indoors.

ELEVATOR: Sierra has only one (which can make you wait), whereas Staybridge has 2.

DVDs: Staybridge has a limited free selection, whereas Sierra has a rental machine (which is not functioning at the moment)

So which is a better deal?
Staybridge is a bit cheaper and with their bountiful food freebies and 24/7 drink pantry could be the better deal, However if your priority is room ambience and gym, Sierra is better.
