I stayed Rui’s apartment for 6 nights. it was great! Rui welcomed to me even though I arrived there after midnight and he taught me everything how to use facilities in there very politely. He was greatly helpful and communicated very frequently. The apartment was really cozy and nice for me as expected. It’s just 80 foots from nearest Metro station entrance and very easy to access everywhere in Porto. The only negative was that the apartment has a bit poor soundproofed. Despite that I would highly recommend!
