I've spent 2 weeks in the small room with the bunk bed and it was quite comfy. The location is truly great, as it is said in the description. It is just on the edge of tourist city centre, so you won't get usual tourist traffic and noises, but it takes you maybe 10-15 minutes to get to the old town, depending on how fast you are. Subway is also very close by, easy transport from & to the airport.
The rooms are very much like in the photos, so there is no surprise there. Kitchen is small, but enough to have breakfast and you get some space in the fridge also.
The only issue might be that you can hear noises from most of the flat, however when everybody keeps it within reasonable range of noise, I wouldn't consider it anyhow annoying.
Overall this is a reasonably priced place in a great, great location for walking trips.
