Philipp was a very friendly and caring host and the flat was great in general.
However, there were some things that should not happen either. The heating in the living room and bath was not working properly, which was quite annoying considering the frosty temperatures outside. Furthermore, the fuse of the water heating device was switching off every 5-10 mins when having a hot shower. So you had to run from the shower into the sleeping room to turn it on again.
Last but not least, freshly renovated is a matching description, as there is still some paint missing at walls and ceiling here and there.
Considering the price we paid per night, I would expect those things being in shape. However, as mentioned before, in general the flat is a nice place to spend some time in Berlin and its location is great.
