David was very understanding and helpful to me and my friend even tho we took a wrong train from the airport and came 2hours late to the apartment. He gave us some nice tips and left us feel very welcome. He had printed the subway map which was very useful!
The apartment was nicely equipped and the area is quite safe and quiet. A big plus is the L4 subway (nearest station 5mins from the apt) that takes you to many of the places where you want to visit. We really liked our stay!
