The apartment is exactly what it looks like in the description and in the pictures, and even better. It is light, warm - and if you want it warmer, you can always rely on the electric radiators. Ondrej is the perfect host, he was welcoming, friendly, clear in his explanations, and his tips about sightseeing and eating or drinking out are excellent.
It is situated in the centre, 50 meters from Mustek metro station in Wenceslas square, and 10-15 minutes walk from the Prague Astronomical Clock. What is best is that, though located in the hub of everything, it faces an interior garden and so it is perfectly quiet!
Bottom line: if you are not into luxurious homes, this the perfect choice!
