Zeki was very hospitable and agreed to let us check-in before the time. He told us every feature of his apartment and provided us with stuff we asked (eg. soap and shampoo).
The apartment is bright with the large rooms. It is staffed with nice beds and historical furniture. The location is very nice - you can walk to the Prague center by the feet. There are a number of bars near the house, also there is Tesco supermarket just around the corner. Underground station is not far.
There is one point you should get used to - inconstant water warmth because of the boiler.
