Maria's place is well located in the art district of Porto, in walking distance of sites, shops and restaurants. The apartment was well equiped with everything we could have needed during the stay.
Maria was very welcoming and communication was very easy.
Although just a note for any light sleepers, you do hear a fair amount of noise from the apartment above and from the street outside (not necessarily during the night, but in the evening and in the morning).
If we come back to Porto, we would definitely consider staying at Maria's apartment again.
