We stayed here for our second week in Porto following a family wedding. It was perfect despite the long steep hill! (Ubers were easy)The views from the apartment were well worth it. We loved being in Gaia it was calmer than old town Porto and yet it was still very easy to access. The apartment is clean and has everything you need although inevitably hot in August . The fan was much appreciated. There are basic shops, cafes and restaurants all close by and off the tourist track who welcomed our pigeon Portugese.
Marta was really helpful and easily contactable. Definitely recommend.
