A hidden gem on Post Street

One block off Union Square, this was a delight. An old property well cared for, we rented a suite and were quite happy with the space, the amenities, the staff, all of it. It felt much more friendly and welcoming than any high-end hotel we've ever stayed in. Heartily recommended.
Patrick, 3-night trip

Would visit again

Friendly and helpful staff, clean room (a bit small but enough for one person), had to ask for ac unit at front desk as rooms only have heater and ceiling fan

Great location in the heart of the city

Great accommodation located in the heart of Union Sqaure. Very convenient to everything. Be aware rooms are not air conditioned so if it’s warm outside then it will be pretty warm in your room. Very clean & nice size rooms.

Howard, 1-night trip

8/10 Very good

The staff was very friendly and accommodating. The room layout was beautiful. Unfortunately the bed was extremely uncomfortable and sinking in the middle. Additionally, it was rather warm and the hotel does not have AC. We appreciated the free continental breakfast in the morning

Mehran, 1-night trip

10/10 Exceptional

Nice hotel for price

Beautiful charming hotel. Extremely clean. Great location. Only negatives would be the ridiculous $25 fee per day for nothing and the breakfast that has only sweet stuff, not even a piece of bacon or a boiled egg. Also, no gym
