We had a great stay at this apartment. It is extremely large and very comfortable. When we were there it was quite hot at 32 degrees Celsius. Although hot outside the bottom level of the apartment is well insulated and remains quite cool. I imagine it would therefore be quite warm in winter. The loft bedrooms on the upper level got warmer during the day, so you would not be able to be up there during the day, but they were well ventilated so cooled down quickly once the sun set. The u-Bahn is right on the doorstep which makes traveling around very quick and easy. We ate most nights up near the zoo which was only 4 stops away and quick to get to. The apartment is on ‘prostitute street’ so that may make some people uncomfortable, but we found it fine. There is no danger and it just adds a bit of a spectacle. We had our 5 and 8 year old children with us and they never asked about the women so I believe that the apartment is child appropriate (some other comments say no). There is a mosque on the bottom level right below the apartment, which is in level 3 (no elevator). When we arrived I was very worried about noise from the mosque but it was not as bad as I feared...but it does mean extra noise that you wouldn’t typically expect in a residential area. The prayers were all very quiet, but as it is a meeting place this means you will get more noise from people gathering, eating, talking, smoking etc. The biggest negative to this apartment is that people will start arriving at 3.30am for morning prayers and buzzing to get in, so it creates a bit of noise (sounds like a prison gate being opened!) that can wake you. This goes through till about 5am with anywhere up to 50 people coming in...so buzzing every 5 minutes or so. Kept me awake the first morning but earplugs meant I was able to sleep through it after that. The bigger noise is created by people walking through the door at the base of the stairs. It swings shut very loudly and slams...and it happens often. It is not a security door and it has a latch, but every time I latched it back to stop the noise, someone immediately undid it...not sure why considering it is not locked and offers no security. I would suggest to the owners that this door needs an automatic closer on it to reduce the noise. Overall a very nice place to stay, very very large, very convenient to access Berlin, but a little noisier than you would expect in typical European city style communal living.
