I don't have a single bad thing to say about this AirBnb. I don't know if I've just had bad luck with AirBnbs or what, but this one stands out as the best one I've ever stayed in. It was clean. Very pretty. The bed was VERY comfortable (especially for Europe). There was A/C in both the living room AND the bedroom (which did not happen in my other AirBnbs in Europe). The location is great—a tiny bit out of the touristy center but barely (and I mean that in a good way). We were also able to store our luggage for a few hours after we checked out, which was very helpful. Don't hesitate to book this apartment for your stay in Porto!
