Krste's place was sparkling clean and a really great location. Easily walkable to all the sights in Prague. The apartment was large and well maintained, and everything was great.
Main issue was the noise. While it's on a quiet street, the building next door was going through a major renovation (as of May 2019) and it was extremely loud during the day (which meant that it was hard to hand at the place at all during the day). At night, the neighbors were loud and the walls and windows are pretty thin, so it was tough at night.
All else was great in the place and we were really happy with it. Small and minimally appointed kitchen, but it worked great, so we were happy with the apartment itself.
