The worst first: A double of your room key is accessible for everyone in the apartment around !! So bye-bye security!
It was very dirty. Especially the room and the bathroom. The bed was full of body hair. The floor hasn't seen any cleaning for a long time. But the worst thing was the bathroom, which wasn't cleaned properly even after I told them. The shower was broken and could not be repaired within my time, because one would have needed pliers to unscrew the shower hose. What I consider to be part of the repertoire for the maintenance of an apartment.
The positive thing is the equipment of the apartment. You find everything you need for cooking, washing etc. and the proximity to the airport.

I am sorry not to be able to give a recommendation. But it is important to me that you know what you are getting into.
