We loved Sanne Maria and Natalie's place, it is comfortable, well equipped (very lovely kitchen) and the perfect home from home.
The location is perfect if you want to be in the heart of bohemian Berlin. So many great cafes, bars and places to eat literally on the doorstep! We felt part of the community after a couple of days, saying hi to staff in places we'd visited as we walked past. There is a food market on Saturdays and a flea market is right there on Sunday too. Its a short walk to two different stations (and another U Bahn another 5 away) and we found it really easy to get to more central / tourist spots. Despite the buzzy area the apartment is calm space to be after a day of exploring.
