Although the building smells really bad and moisture is everywhere, the flat is bearable and less smelly. The building is located next to a train station and I don't know why and how but there were really a lot of noise during the night that could really wake you up. Was it trash truck or something else, I don't remember but I did wake up.
Also, the WiFi didn't work for the first day and started to work on the second day magically...
The kitchen equipments looked old and not clean at first sight.
Overall, it was a cheap alternative and a really close alternative to the main city attractions. For a family, it could get a bit complex but for a couple with no kids or a single, it should be OK...
