We had a very nice time in Prague. Petr, Martin's friend, came to pick us up at the airport, and gave some nice tips on the way to the apartment. The apartment is located not in the very central area, but still very accessible to public transport (tram/M), and we found it very easy and a nice area if you are not the regular tourist type of person - nice bar/restaurant/coffee places.
The apartment looked very good! Even better then the photos, and Martin left everything very clean and explained all that we needed to know about it. He even had this little guide book for important things to know around the house. We came for check in a little late, around 10pm, and it went smoothly.
We really liked our stay in Prague, and this is a first very good experience for us at AirBnB.
Definitely recommend this place for others!
