I had a great time, all things considered! The location is great (very close to the big park, short walk to the city center and metro stations). I could even check in many hours earlier than planned!
The only thing that bothered me was that people were often smoking in the courtyard adjacent to my room, so I couldn't open my window whenever I wanted to. As a non-smoker, this was unpleasant.
Beyond that though, everything was fine!
