Great!
This was one of the best beds we've slept in at a hotel. Really luxurious! The room was not large, but not tiny - we were happy with it. The location was very convenient (right by Grand Central Station, and of course, the library). The rooftop bar was great - cozy with some very tasty cocktails. Between that, the lovely breakfast, the wine and cheese, and the friendly staff, we were quite pampered. It was our anniversary, and we had a bottle of prosecco and chocolates waiting for us when we arrived :)
The subject-per-room was a lot of fun and not overdone/over the top. (We were in the Slavic room). My one issue is that Hungary isn't a Slavic country, and if that is the only complaint, hopefully you can tell how nice a stay we had...
