Me and my partner spent five nights in Room 3 and we are very content with our stay. The room is rather small but that was not a problem for us. We were there in early March and since the apartment has no heating it was very cold in the room, so we highly recommend that you ask for a heater (5€ per two days) if you go in winter. It's a big apartment with plenty of rooms which were all occupied at the time. The kitchen was spacious and fully equipped. Both kitchen and bathrooms were very clean, Karem seems to take good care of the apartment and we really appreciated that. The location is not very central but as we like to walk, we counted that it takes 40 minutes to walk to the city centre. There's however a metro station 5 minutes from the apartment. Karem is a really kind and sweet person. She got us a heater when we asked for it, and she let us check in earlier because we arrived very early to Porto. We recommend this host :)
