The apartment was very clean and the modern design was excellently suited to not only a home but as comfortable environment for guests. The facilities , wifi , toilets/ showers and the like were of a great quality. The host Günter was very hospitable and open to communication including letting me stay an extra night which I had not planned for. This was greatly appreciated !
In conclusion this is a desirable place to stay in an awesome part of Berlin - thank you Günter !
