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

Le petit-déjeuner devrait être plus varié. Les gobelets devraient être plus grands. Il faudrait des chaises dans les chambres car, parfois, la salle du petit déjeuner étant petite, elle est complète. Nous pourrions alors prendre notre petit déjeuner dans notre chambre.

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.

As someone that expects excellent quality stay, this spot met my expectations, and more! Spacious rooms, decent range of free breakfast menu, housekeeping staff that goes above and beyond. Please support hotels like this over big chains.
