Maybe check in need to be improve more smooth, so we not wait almost 20 min outside the door for waiting the host, although we already keep in touch in airbnb message, but key of the apartment still late. for the apartment, nice apartment, old, artistic. Only the stairs the problem for the traveller who bring big luggages, but its already mention in the app, so no problem. And the air-condition are only 2, in the main room and living room. Thanks
