We stayed 4 nights at Sabrina's place, it was great, only positive comments! Looking at the map, you see Fehrbelliner Platz is not in the middle of the tourist attractions, but metro is 3 minutes walk and takes you quickly to everywhere. Note there's 2 lines in that station. And it's nice to be away from the tourist buzz, and live in an actual residential area/street, like a Berliner. Also getting in and out to the airport was really easy and convenient. It's really worth staying in that area, we did not try the restaurants or bars because we left early and returned late, but there's snacks and breakfast options morning at the metro station itself, and if you return late there's the Azerbaijan Döner in front of the supermarket with fast foods, it closes after 23:00hrs. Sabrina's house is very big, and guests have a lot of privacy. And it's good to have her living with us at the house, she is around, friendly, always available. Great person with warm heart, makes us feel at home. Many places now in the big cities are "fake" airbnbs, where you actually do not get to meet the host (which is not really an issue when you are sightseeing all day).
