Cute apartment, smaller than it appears on the picture. The place itself was wonderful in a nice neighborhood in Berlin.
We had some problem with the internet and communication with the host. We contacted the host before booking and confirmed that the internet would be fast enough since we needed a place where we could work at. The host assured us that the internet is fast enough. When we got to the apartment, the speed we were getting were around 0.4 mbps. It was so slow that Google maps won't even load. When we contacted the host for help, instead of offering real help in case the internet speed doesn't improve, he told us that there are plenty of internet cafes nearby. The internet speed did not improve during our 5 day stay in the apartment. Luckily I had a friend in Berlin who let us work in his office space so we ended up spending majority of our time there instead of in this apartment that we booked.
Another thing was that it got pretty chilly in Berlin during our stay but the heater in the apartment doesn't work from April to October.
