"The hotel is dated and inconvenient. Noise from the hallway pours into the rooms. There is no decent lounge area for people to congregate. The doorman is absolutely useless- won’t even hold the door or help with baggage. The service in the restaurant was mediocre. The front desk does not look ..."

Chancellor Hotel on Union Square

Travelocity Verified Review

"I enjoyed my stay. Location was very central and easily walkable. There was some construction going on during my stay so it made it hard to recognize from the street as the sign was covered. I am rating it a 4 because there are really no amenities. No bar (was closed), no restaurant, no gym, no A/C, and the parking is a block away. However, I liked the old time charm/character to the place, the bed was comfy, the staff was pretty helpful, even though sometimes I had to wait a bit for the bell hop. When I did food delivery, it always came very quickly to the hotel since the location was central to a lot of places."
