Overall, the apartment is very nice, well equipped, clean and clear. The place is quiet and well served by public transport. To be perfect just missing something to help cope with the summer heat in Berlin, which in 2014 was stifling. At least one fan is essential.
But I do two caveats:
1 - I have stayed with my family (wife and two daughters, 16 and 20 years, with weight and height from average to short). I consulted the landlord on the use of the couch and he assured me that was adequate for two adults, which is not true. The sofa sleeps a maximum of two small children, but by no means two adults, which made our stay very uncomfortable for my daughters. Thus, we only recommend the apartment for a couple without children, or with small children.
2 - The price agreed by Airbnb included all fees and expenses. But on the second day of stay when the landlord made ​​a visit, charged me an extra cost by 12,00 euros for an alleged municipal tax earlier this year. The booking was made on March 25 - so when this alleged tax was in effect. After that, there were several contacts with the landlord. And there was never any mention of this extra cost. And in the Airbnb announcement, this tax is yet not mentioned.
Although the amount is small, it serves to discredit the landlord and Airbnb itself. The price and the agreed conditions should be strictly complied by both parties, no surprises this type.
