Unfortunately, we were quite deceived by the pictures and descriptions on the website!
First and foremost, the conditions of two the flats we could see were much worse than published on the airbnb website. The images give the impression that the flats are brand new having clean and stylish furnitures, which is definitely not the case. The air conditioning system is old and makes a lot of noice. Furthermore, the mattress was extremely uncomfortable, which is because of the old spring bed. For sure, certain springs will make you and your back annoyed by the next morning ;). The most critical point, however, was the cigarette smoke smell everywhere in the flat! If you are not a smoker that may disturb a cosy evening. Moreover, the host was not able to speak English, which of course is an issue if you want to communicate about certain issues with your accommodation.
Despite this negative points, the host tried to help us and offered us another room, which was slightly better, at least with respect to the bad smell as well as the street noice. The cancellation of the second night went without any problem, which we appreciated!
