This apartment is a great little place for a stay in Berlin. Very close to the U-Bahn, so access to city centre and other places of interest is very easy. The neighbourhood is great too; with shops very close by, and parks also to chill out at the end of a busy sightseeing day.
The place itself is very clean and very cosy, with basic but sufficient equipment.
One thing to note though is that this place wouldn't be suitable to light sleepers. The bedroom windows are street side and there can be a lot of traffic.And also it's very close to the airport, so planes flying low above are a regular occurrence. I personally don't mind, as I can sleep pretty much through anything; but I believe it's worth mentioning.
