This is my first time to write something about the apartment. I would really like to share my experience here.
The explanation of the location was very very weak. First, they didn't tell me the number of the apartment, and because of their ambiguous explanation, I had to wait outside with my heavy luggages.
The information about the wifi in the app was wrong (also there were no extra explanation) so I had to search for it all by myself.
Whenever I asked for the way to open the door with the key, they were irresponsible. They just said to open it "slowly". So I had to ask other people inside the apartment for help.
I've been using several airbnbs and this was my worst experience. The apartment itself was convenient and cozy, those instructions were terrible.
