We had a lovely stay in Rui's apartment in Porto. The apartment is really nice and clean, as you can see in the photos. It is conviniently located, you can reach everything by foot, and there is quite a few good restaurants in the neighbourhood (Museu d'Avo, RUA, Camafeu). Oh, and there is a nice cafe/pastry shop in the street where you can get really cheap and tasty breakfast! The apartment is located in the back of the street, which is nice and quiet. Rui has been a great host from the beginning, great communication and good recommendations.
I would highly recommend this apartment to anyone visiting Porto!
