The place is really stylish and very central in a fun neighborhood.
There were 2 downsides to it while we were there.
1) The wifi was incredibly slow and you could only connect to it while in the kitchen standing next to the dongle itself. It was completely unusable to work, so you will have to find a cafe nearby. Luckily, Berlin has no shortage of them!
2) There was construction happening on the facade of the house. This meant that we were woken up several times at 6am (during the week). We reported it to the hosts, who let the construction crew know. They promised they wouldn't start anymore until 8am but unfortunately they did. So be aware, if you are coming during the week and aren't an early bird, this might be your morning alarm.
Otherwise, the place and the hosts communication was really great!
