Our 10 day stay at Peterson's was wonderful. The house is clean and very close to metro and bus stops. Also, the area itself had supermarkets, bakeries, café's and a few restaurants too. Peterson was the best host we could've wished for, he is a very friendly and fun(ny) person and we had many laughs and good times with him. He made our stay very pleasant!
Only negative thing I can think of was the streets were quite noisy but we had earplugs and weren't too bothered by that.
All in all, very happy with our stay and definitely recommend anyone going to Porto to stay at Peterson's!
