Bad experience with the host. He promises availability from 10am to 10pm but this is not the case. We arranged the arrival time for the delivery of the keys with him and, when we were delayed 10 minutes due to a bus strike in Berlin (of which he did not inform us and it was very important), he decided to leave, without giving us any alternative, he just told us that he had a "meeting". As soon as we arrived at the airport, we warned him of the strike and of the time we would be late. The result: two hours waiting for him to come again to give us the keys with our luggage at the aparment`s main door raining.
The apartment has no curtains to prevent light from entering so it was difficult to sleep at sunrise. There was a lot of noise during the day because there were works in the building.
It is for 2 people, not for 4, as indicated in the apartment's description (the other two beds are sofas) and are in the same room (it is a loft).
It has a very good location, in the Jewish quarter, with several places to eat and to have a drink.
After the check-out, we were able to leave our luggage in a storeroom of the building.
