Quite a nice place, great value for money, good for solo travelers. The room is small, similar to a hotel room, but you have everything you need. It was also very quiet in the room, which is not typical in the center of Prague. Check in was super easy, the building reception was aware of my arrival and had a key card ready. Nice.
One issue is there are no curtains on the windows, so others can potentially see into the room from across the courtyard. The lack of curtains was clear from the pictures, however, so no surprise. But take note, if you are thinking of booking with a significant other and would prefer privacy, you may want to find another option.
