The room is even bigger than in looks in the pictures. I stayed there whit my bf for 2 months and it was a very good experience, the other roommates were nice and polite. It’s a great way to make friends.
The location is great (close to subway stations, supermarkets and touristic points), although very noisy! The street is full of bars and night clubs so expect a lot of people passing by all the time. Most of the time it didn’t bothered us, but if you need silence to sleep it might be a problem.
As for the rest of the apartment, the space is as good as it shows — but I do think it could be better equipped, in general. Also, cleaning was not the best.
At last, Joerg is a great host and will sure attend to your needs and doughts.
