The apartment was dirty when we arrived. There were food residues in the sink, a lot of hair and dirt on the floor and on the sofa, and the kitchen hob was dirty and greasy. The host didn't provide the essentials, namely toilet paper and towels. It is actually specified in the listing, so my bad for taking it for granted. The wardrobes and cupboards are full with the host's private belongings, so there is no place for the guest to put clothes. The host was not there at the check in to sort all of these issues.
For this reason, we decided to book a hotel and not to use the apartment for our stay. It's a shame, since the apartment is actually nice and in a good position, just a hundred meters away from the metro station and few steps away from a supermarket.
