Hermann's flat is just as advertised. The main room has a double bad and an extensible couch that can fit too people, with an extra queen size in an adjacent room, separated by a curtain.
Great for traveling with friends or family.
The location is also fitting, as the flat is very close to the brown subway line. The metro tracks are really close but for us that wasn't a problem, even with windows open all night there wasn't too much noise. Note that you might want to bring a mosquito repellent as the windows don't a protective screen.
All in all, it was a great stay and we were happy to find it! Many thanks to Hermann for being available and responding quickly.
