Great location, amazing views, and pretty cool layout. Very spacious, and super central. Couldn't recommend it more really. Check in was very easy and we were given a good introduction to the city by the friend of Sergey.
It really feels like a pretty special place, for very good value as a large group of people. One downside is the number of stairs to get up there, but if there weren't so many stairs then there wouldn't be such a good view!
