Communication with George before arrival was very easy and fast by airbnb e-mail and with text messages.
George picked us up from the airport, which was very convenient for us (1 of us being handicapped). He also - on request dropped us of again on our way back and provided some more assistance upon request.
We loved the apartment it self: it was very spacious, clean and mostly everything we needed was there.
But mostly: it proved to be at an excellent location to explore the city. The main bridge, the castle, some museums, little parks and lots of restaurants are all very near by.
Though central, it is a very quiet neighbourhood: There is no noise from the streets preventing you to sleep at night.
I certainly recommend staying in this apartment.
