The apartment was managed by a company instead of the real host. All messages you got after you booked the apartment were so official and sometimes has incorrect information. In our case the last message we got before we arrived Porto asked to go the help center of the manage company instead of the apartment. But when we arrived there the help center told us the checkin of the apartment we booked should happen in the apartment. When we arrived the apartment 5 minutes behind schedule, there is no one there and no one answered the phone of the host. We waited 30 minutes aside the street and was then a staff of the company came and told me he was late because he was in another apartment checking in another guest.
Apart from that the rest was the same as described in the home page.
