Really nice hotel. Even though the rooms are old, they are kept so nice and clean. The hotel is within walkable distance of many things in union square. Public transportation is also nearby so getting around the city is easy.

Ac didn't work in our room and when we showered we realized the shampoo & conditioner were completely empty and had to call the front desk to refill them. Also didn't read that you have to pay for the valet parking which was almost half of what the room cost.

I docked stars for cleanliness because the shower tile had a good amount of mold in between tiles which I am careful of both for cleanliness and it can trigger my asthma. The positive is it has a Michelin starred Thai restaurant on site, which was very busy and delicious tho I caution it is spicey. ...
