As described, it's definitely up lots of stairs! As others said though, this didn't bother us as we only did them once or maybe twice a day because we were out sightseeing. Maybe flat is slightly smaller than the photos made it look? The bed is under the eaves, so the person on the inside near the wall has to be mindful not to sit up quickly and hit their head if tall...we managed not to. The room is immediately adjacent to the owners' flat, so we occasionally heard normal noises of people moving around next door, but it wasn't disturbing. Very clean. Bed very comfortable and shower great - better than many hotel showers we've experienced. Etienne made check in easy and had some local restaurant recommendations and a map for the first night which was handy. Our first night the weather was extremely windy and we were woken up by the bathroom fan being blown from the outside, but that was unusual. The room has blackout blinds too, so we slept really well other than that, quiet and cosy. Well connected by trams and S bahn with the rest of the city. Would use again.
