Great place to stay in Prague. My dad and I had lots of room, a very clean, functional kitchen and bathroom, and a balcony overlooking the building's inner courtyard.
The location is a block from the main tourists areas, which is great because you can go to great local cafes and the nearby park without falling into tourists traps, but the touristy stuff is just a block away if you want to check it out.
We found that we only had sheets for one bed, but the hosts responded immediately to a late-evening text message and sent someone to set up the sofa bed. Other guests in adjoining balconies can be a bit noisy but the sliding doors are relatively soundproof, so no big deal.
