Upon arrival, I had no information back from the "owner", and no replies for over three hours. I had to wait in the bar nearby for someone to get back. The phone on the Airbnb site I found was to the accountancy of the company that rents the flat, and after a few more connections, I finally got the message on the key box plus codes and could enter the apt. Ringed straight back with all details about the state of apt, sending as well pictures and video. A number of utensils not working or missing plus the whole flat in need of repairs and refreshing (cigarette odour was significant). For the first 5 days, we didn't have the key to the entrance door and only one for the apartment (2ppl) so we had to orchestrate going outs and ask neighbours to let us in as well. Communication with the company was ineffective and very difficult. Despite that, the company owns the whole building and rents all the apartments there, there was not even one cleaning of the staircase during those ca. three weeks - we cut our stay from three months to three weeks, as soon as we were able to secure another flat.
Positives - location is very central, with brilliant restaurants and cafes around, and the apartment is equipped with basics (though repairs are in order), the handyman for the repairs was the nice person and the only one effective.
