Nice hotel for price
Beautiful charming hotel. Extremely clean. Great location. Only negatives would be the ridiculous $25 fee per day for nothing and the breakfast that has only sweet stuff, not even a piece of bacon or a boiled egg. Also, no gym

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.
