Great Location only minutes from the nearest U station, perfect for us getting around during the Berlin Marathon.
The space is architecturally stunning, clean and tidy but a little oppressive due to the nature of the location of the apartment. Being at street level your privacy is compromised if you have the blinds and windows open, so you have to keep these closed, more so at night as there are bars and restaurants nearby.
The facilities are good, although there is no toilet door, so those couples of a less intimate nature be warned!!
Check-in and check-out was very easy. We would definitely stay here again for a couple of nights in Berlin.
