We really enjoyed our stay at Helena and Artur's place. We had a late check-in so we didn't get to meet them in person unfortunately, but they were very flexible and accommodating. The lady who welcomed us to the apartment, Lucia, was very friendly and gave us great recommendations. The apartment is exactly as pictured - spacious, nicely decorated and clean. Also centrally located, we walked everywhere. We had a great time in the apartment and Porto :)
