Beautiful hotel and a great centralized location. The room was always clean and the staff was out of this world. The only thing is, if you didn't get to the continental breakfast when it opened, you will likely not get anything as they do not restock the pastries or refill the coffee.

Great small hotel on Union Square

Great small, old style hotel conveniently located steps away from Union Square, shops, and all the transport links you need. The rooms are huge, rooms and clean with all the amenities you need. Also nice and quiet. The breakfast was also handy.

I was skeptical at first but it was alright. Took some time to get use to. Overall everything was good. The parking is the only issue, you have to park around the corner for $35.00 but if you go out more than once they charge you $10 each time you go out.

Last minute. Fit the purpose. I just don’t think it was worth the price, since I got charged with resort fees + parking wasn’t in the premises.
