I tend to not to write bad feedback but this time I feel like I should do it.
First of all, the check in experience was bad. To enter the flat, I was given a door code that did not work. I called the host four times when I arrived because I couldn't get into my room, but he only called me back one or two hours later, so I had to contact Airbnb support…
The room was also gloomy and poorly ventilated due to a filthy little window it had. There was virtually no sound isolation, and I could hear absolutely everything. It felt like I was sharing a room with other guests from the next room. In the morning, I could also hear everyone farting in the common bathroom situated next to the room. :) Finally, the common bathrooms, despite being cleaned on a regular basis, were full of mould and in desperate need of restoration.
The only reason I stayed the whole time was because there were no other options due to the websummit conference. and yes, I understand it is a budget option, but if you want at least a little bit of comfort, PLEASE AVOID THIS ROOM AT ALL COSTS.
