The keys are actually not in the mailbox as instructed, we stuck there like half an hour until someone came from the building and assist us to the room, we called the host but nobody was answering the calls. The other morning we saw another group of people stuck there in front of the mail box for the keys apparently the host should update the instructions otherwise it is not a good arrival experience. The room is quit big and clean that’s exactly as shown in the photos, probably the windows has been kept closed for sometime and the air circulation is bad, plus there’s a very stinky smell coming from the toilet sewer, is terrible so we immediately opened the window and tried to let the smell out as soon as possible. because it was on the very busy street, although it was on the 5th floor, we still felt that the car was passing by us, and people was like talking next to you. Or we had to bare with the smells or enjoy a IMAX surround sound experience if we did not shut the doors and windows. Except these everything is nice, and the apartment has LIFT so it was very convenient for us with 7 big luggage. Btw. Airbnb customer service helped to communicate with our host, and the issues we mentioned was solved the other day or in 2 days, and the smell had been cleared out like in the other day we lived in.
