Jiri is a great host, both through email and text as well as face-to-face. The appartment is on a perfect location with nice shops, bars, breakfast places and restaurants in the area, there is a great restaurant just down stairs if you like to try local Czech food, less than a minute walk to the street market just behind the building if you like to buy fresh fruit, it is 2 minutes from the main bar/club street, and 3 minutes walk to old town, 10 minutes from Palladium shopping center where you can find another street market next to it for local pasteries or sausage stand or underground subway for commuting to or from airport with only 32 CZK and It is 20 minutes walk from main train station.
The apartment itself had everything we needed, it was in 3rd floor with no elevator which was not a big deal for us,the pictures are exact, and we appreciated the fact that there are two separate rooms (which can both be closed) plus kitchen and bathroom. I can recommend the apartment to anyone who wants to visit Prague, both for going out as well as for seeing the beautiful city.
