Great location!

The building is old, which we found charming. The service was good, helpful and professional. Perfect location if Union Square is what you want, great restaurants and shopping close by and very “walkable”. We prefer to stay in this area over any other in the city.

Overpriced, too small, bad smell in the room, dirty carpet, tiny elevator and hallways and the valet is NOT included. Galleria Park Hotel had the same price, a great lobby, spacious clean rooms, and valet parking. I will not stay at Inn at Union Square again. Thank you!
