We met Emil to get the keys in his office. He was friendly and really wanted to give us some tips about things to do in the city. Unfortunately we didn't have much questions to ask him :)
The apartment was like described in the ad. Really close from the city center so that we could reach everything by foot. There was enough sleeping place for 3 people but just 2 chairs to sit around the table (not a problem because the bed was quite close). The kitchen was also well furnished even with tea and coffee. The only negative point is that the apartement is quite dark due to the other buildings in front of the window. But all in one it was a clean, comfortable and useful place to enjoy our 2 days in Prague. Thanks Emil and Olga :)
