3 out of 5 stars for Martin's flat...
The flat is placed in a great area, close to U-Bahn, bars, clubs, restaurants, shopping and not that far away from Berlin centrum!
We came by car, could find a parking spot every day close to the flat.
Martin's flat is a nice one, kitchen with plenty of space for cooking and eating, toilet and shower with more than enough hot water for 2 persons showers... The room that Martin have is a nice big room, the bed was comfortable, with good light, no noise from street, neighbors or neighborhood.
Internet speed is fine, we didn't have any problem steaming movies from Netflix, surfing etc.
We can't complain about the cleaning because, some one forgot to clean the place before we arrived, but we had no problems with the dust, the reason why I'm mentioning this is, that when we saw the price we could read, that we had to pay few € for cleaning ;-)
Only pity was, the the flat smelled of cigarette smoke, but after several hours with opened windows in the entire flat, we could fall a sleep with almost none smoke smell, and our clothes didn't smell the day after. Perhaps we are very sensitive because we have never smoked :-/ but nevertheless- we enjoyed our New Year stay in Martin's flat a lot, and for sure we will recommend it to all others, we would also like to rent the flat some other time, perhaps during summertime, as Siberian winter cold arrived Berlin during the last days of our stay, but this we can't blame Martin for, as it's winter time now... But the flat was heated up easily!
We had the entire flat ourselves because Martin's roommate wasn't home during our stay, so we can't tell anything about her, but since Martin seems like a very nice guy, our guess is, that she is a nice person too..! :-)
Martin made a list of great places to visit, this is much appreciated.
