The apartment is lovely, with plenty of light and clean.
It can be helpful for travelers to know that the location doesn't correspond to reality: the map's circle for the location is very near Boavista (Praça Mouzinho de Alburquerque) but actually the apartment is closer to Praça da Républica.
It is mentioned on the site that the apartment is on the second floor but it would be a good idea to make clear that there's no lift, as it can be a problem for some guests.
It is suggested to guests, on the departure's day, to make sure the entrance door is unlocked before leaving the key in the apartment, as apparently it's possible that somebody from the building locks the main door during the night. I found that rather disturbing as in a case of an emergency it may be a problem. It was also inconvenient.
