It was my 1st AirBnB experience but I couldn't have asked for a better host. We stayed at the apartment with 4, but one of us arrived earlier in the day which was no problem at all. He met up with my friend, let him drop of his luggage and gave him some tips on what to see. Martin was very helpful and responded very quick to my messages during our stay.

The apartment is comfortable, spacious and clean and basic stuff like soap, towels, coffee etc. are provided.
Also.. It was quite hot during our stay, but the temperature inside was very pleasant.
It's located in a great neighborhood close to S and U bahn, Victoria Park, restaurants (nice pizza place around the corner.. so cheat day-o-plenty;) and supermarkets. We rented bikes from a place across the street and where able to cover plenty of ground from here.

We had a great time and would definitely stay here again next time we come to Berlin.
