David was very helpful, fast and easy communication, flexibility regarding check-in, he made our stay really easyier. The flat was nice and clean, with a view. Kitchen and bathroom were well equipped. Location is good: His place is close to the metro/subway station, almost all lines passing by, so trains are going really frequently. City centre altogether 6 stations. You can reach even the airport with one line front here. I would definitely recommend to stay at his place.
