After 30 minutes of checking in I cancelled my reservation because the apartment was not clean to the level I expect from an Airbnb flat. There was dirty soap scum on the lip of the bathtub and soap scum on the tile walls surrounding the tub. The glass partition at the front of the tub was also very dirty, like it had not been cleaned in a while or between showers. The apartment was also extremely dusty to the point of inflaming my sinuses and caused me to have a sever headache. The place needs a good vacuuming, especially under the sofa in the corner because from the bed you can see the amount of dust that has accumulated. Additionally there was only a small amount of toilet paper on the roll when I checked in with no back up paper provided. I searched in every cabinet in the apartment but found no additional rolls. I don't understand why the cleaners didn't leave another roll out in plain sight considering the small amount of paper left on the one in the bathroom. The small glass coffee table next to the sofa obviously had not been cleaned in a while. It contained many finger prints. Overall the apartment needs a proper and thorough cleaning by people who know and care about their work. Also the available WIFI network (different than the one listed on the check-in instructions) was REALLY slow. Finally, the location and lack of adequate amenities made this apartment not worth the nightly rental fee. Once I cancelled the reservation, I moved to a hotel in Central Berlin at a lower rate. It was extremely clean and breakfast was included!
