Lovely space in a great location central to all the Prague sites! The apartment has high ceilings, and the main room is spacious and well-equipped.
I'm giving a lower rating because I did not sleep well here - you hear every car rumbling by on the cobblestones outside, with the larger cars shaking the windows. Additionally, the curtains are thin so the apartment is permanently lit up, with further lights from passing headlights. That said, if you are a sound sleeper, I don't think you'd find any down sides to this place, and it's a great value.
Also lowered the rating because management was not great - the operating company didn't know the heating was fixed, and left me shivering in freezing weather for several hours (that said, the heating works great now). The tv was also not working and I didn't get any help beyond "use the remote".
