The apartment is located very central and you can reach everything in walking distance. As there is a bus station on the street and the windows are not good, it is noisy.
The WLAN didn‘t work properly.
The door of the shower did not close, so you have water on the floor after using the shower and not enough towels to clean.
The Check-in was easy; the key needs to be picked up from the headoffice.
Unfortunately this is not a really AirBnb experience, as the host is a company and not a single person.
It was okay for the few days we stayed in Porto but I would not recommend it.
