I spent one night at Christophe's and Romana's place. The room was exactly as in the pictures and everything was super clean (the bathroom included).
The check-in and out times have been flexible (I could easily communicate with them) and I could even leave my luggage in the house after the check-out.
They have been welcoming and nice (Kirra included :) ).
The location is not ideal if you plan to walk to the centre but there's a metro station at 10 min walking from the place.
