For those who like to live on trips in old buildings, this hotel is a very good option for the price + location ratio. And also, if breakfast, lunch and dinner at the hotel are not important to you (there is a place to have lunch and dinner in Prague, believe me).
There are disadvantages (lack of an elevator), but the wonderful view from the window on Mostetskaya Street and the proximity to all the sights cover these disadvantages ...
We really like this hotel, we stayed there twice.
