Great people makes great country! First of all, Sarah & Sebastião and their friends are very kind, friendly and positive people! It was pleasure to stay in their home for 3 days.
Nice location, not far from metro, bus station and railway station. You may get everywhere just by short walk. You'll get clean comfortable room and hospitable neighbors - Sarah & Sebastião. If you are lucky, you'll have a chance to meet their friends, too :) guys will help you and guide about Porto and interesting places.
Kindly recommend this place and definitely will ask for accommodation there next time in Porto!
