The apartment is beautiful and finely decorated. It's very clean and the kitchen is equipped with all necessary amenities. The location is great, because all main attractions are within a 15 minute walk. All perfect, if it wasn't for the room temperature and the noise coming from the street. In the apartment there's no heating, but just A/C, which may be good in the summer but not in the winter. If you want the living room not to be too cold you have to switch the air conditioner on, but if you do the bedrooms will get too hot. It's not easy to find the right balance, so you'll either be too cold downstairs or too hot upstairs. What makes things worse however is the noise coming from the street. When I read the many reviews about this I thought "Come on, it can't be that bad"... Yes, it can! People in Porto seem never to be sleeping. From the apartment you can hear people screeming and shouting, playing very loud music and car horns all night long. Even if you accidentally manage to fall asleep, you'll be waken up repeatedly during the night. If I put together all the short fractions of sleep we managed to get, we probably slept 1 night out of 3. On check-out day we were just happy to leave, looking forward to getting some rest somewhere else!
As for the host, we never got to meet him, but he sent us very detailed explanations about self check-in and some tips on things to see and to do.
