We enjoyed our stay at Marisa's Airbnb in Porto. The rooms were clean, comfortable, nicely decorated, and made for a comfortable stay. The apartment is in a perfect location on a very nice cobblestone/tile walking street, with shops, restaurants, and hotels. The street is blocked off to cars.
Marisa always responded to our requests before the end of the day.
There are a few things about the Airbnb that future guests should be aware of. The Airbnb is not a traditional house. Instead it consists of six independent apartments in two buildings, separated by a lovely garden area. Each apartment has it's own key, and (with one exception, described later) consists of a single room with a bed, small table, couch, and a kitchen area adjacent to the bed. Each apartment has it's own private bath with a shower. One of the apartments has a smaller bedroom than the others with a separate living room that has a large table, a kitchen area, a couch, and multiple comfortable chairs. There is a picture of this room in the listing, and it looks like the common living room or dining room - but it is actually a room in one of the six apartments - so the other five apartments don't have easy access to this room unless the person(s) in that apartment leave their door open, and even then people in the other building will have to walk outside through the central garden area to get to the "living room."
We were travelling as a family of seven, and were expecting a traditional house, where people could easily walk from their bedroom to the living room, and hang out there; but the layout of this Airbnb made that difficult. And since it was raining during most of our stay, the outdoor garden area was not really usable. The listing clearly states that this Airbnb is six separate apartments, but it does not make it clear that they are in separate buildings; nor does it make clear that the pictured "living room" is actually inside one of the six apartments.
Nonetheless we had a good time in this Airbnb, which is located right on the center of things, with easy access to lots of great restaurants and the sites of Porto. We would definitely recommend to others.
