We 're a couple of 60+ and booked for the first time through airbnb and we're really satisfied about the whole proces. We stayed in the appartement for a week and had such a good time. Everything was as aspected! The appartment was cosy, comfortable and fully equipped. We rented bikes at the fahrradstation at Kolwitzstr. you can book in advance and the bikes are great. We saw a lot of Berlin this way. We enjoyed Prenzlauerberg a lot, thanks to the marvelous weather we tried a lot of the terraces (our favorite is the one in the friedrichshainpark), great!! If you are visiting on sunday the Mauerpark is really great, we spent almost the whole sunday here.
And Sabine is a real darling, informing, (while she was out of Berlin) whether everything went oke, and giving us advice about how tot get there, things to do, etc.
We slept really good, the apartment is so quiet, which is nice after roaming around all day through the streets of Berlin.

When looking for a great place we recommend the apartment of Sabine and we hope to be back again!
Thanks again Sabine!!
