The location was perfect. I was able to check in early. My room was upgraded. Esly checked me in and was very helpful. Housekeeping was great. The provided breakfast was a wonderful way to start the day. There were bagels, pastries, yogurt, juice, coffee and a great selection of fruit. This was the perfect stay for me.

The Inn at Union Square is a gem! Conveniently located, well maintained, and very accommodating staff. Room and bathroom were spotless, and the bed was comfortable. The size of the room is just right especially if you’re spending most of your time out and about. Would highly recommend.

The property is just old. Looks a little bit haunted. The continental breakfast is bagels and pastries. No ac the room was hot and only a fan to cool it.
