Price quality ratio is excellent. The app is spatious and truly one of the most original places I've ever stayed in. It has character and the details keep surprising you.
Location wise this place is perfect for people who prefer to be a bit away from the shopping streets and restaurants, however it's only a 15 minute metro ride away from Alexanderplatz, Kreuzberg and Mitte if you want to go sightseeing. And only a 2 minute walk from the former Tempelhof Flughafen, which is definitely a must if you want to do something different.

Practicalities: Wifi connection works fast, metro, shopping for food, atm machines, pharmacy are all just a 5 minute walk away.
The place is very clean, towels, sheets, covers are all there, but I'd recommend to bring a sleeping mask for those who are not used to sleeping in a spacious and light appartment :-)
