This is an outstanding apartment that can easily accommodate four travelers (six if scheduling the single bathroom can be accommodated). We (a family of three) loved our stay at Carlos & Christina's apartment. The location: perfect! The hospitality: In the top category of AirBnB stays we've had (around two dozen at this point). The only note to be clear on is that the apartment is a fourth floor walk-up (not an issue to us as we loved both the feel of the building and the exercise of the stairs). Now, if you've signed on for Porto and its steep climbs, the apartment stairs should be no matter, but for those who like to fall right in to an accommodation, a mention is valid. The apartment itself is clean, well-thought and provided us nothing but comfort. Carlos & Christina are wonderful hosts who clearly love their city and introducing travelers to the charms of northern Portugal. Anytime we are heading back to Porto and this apartment is available, we will have found our home for the length of our stay.
