Good ..... but not perfect
The nine-zero was our first hotel for our recent 10 day trip to the USA
We were very much looking forward to staying at the boutique hotel - especially when even before we left the UK we were asked for a picture the hotel would pint out and put in our room to make us feel at home. Unfortunately, though sent, this never appeared in our room.
The room was very comfortable. The $10 mini-bar credit was a good idea though didn't go very far ( packet of chips and some cookies). 
Shower was a perfect power shower - and it NOT being in a bath was great. We both much prefer not having a bath!
Breakfast was excellent and the table staff were very attentive. It was very disappointing that the KOprime restaurant no longer exists - room service is not a good alternative in a relatively small room! The hotel needs to let customers there is no restaurant option any more.
We also were double charged for our room - which had been Pre-paid. Fortunately we were back in Boston a few days later and the staff rapidly refunded us when we called in to check - sadly due to exchange rates this error cost us £26!
So a pleasant stay but they dropped the ball in a couple of ways
