Great studio apartment, in a very good location. The layout of the studio was great & it felt very spacious. Walkable to all the main spots Porto has to offer.
As the apartment is in an old building, you do hear creaks/movements/ chats of the neighbors, but they were generally quiet when it came to bed time.
Unfortunately there must have been a little crack in the exterior walls as some hard working ants found their way in to the kitchen. Not a big deal, but would have been if I was there for longer. I believe they were getting it sorted.
Overall, great stay and I would definitely return.
