The location is really unbeatable. Walking distance to everything and only a block from Charles Bridge. Jan was really nice letting me into the apartment and showing me everything. It's a small studio just like the pictures but actually felt bigger than I thought it would be. Very basic and bare but was fine for my needs. The bed linens seemed old but I didn't mind b/c I know they were clean - just know that this is not like a hotel or a modern apartment. Everything worked though I did have some problems with the Internet that seemed usual for the area, and I did have to buy a roll of toilet paper.
It's really all about the location and having a quiet comfortable home base, not about the amenities. I would recommend because my experience in Prague was great and it was so nice to have a central location!!
