Beautiful apartment in a central yet quiet location! Just a few minutes walk from the core tourist parts of Porto. The apartment was charmingly decorated and spotlessly clean. Both the beds/linens were quite comfortable, although I'm not sure I'd want to put two people on the pull out couch comfy for one, but likely a squeeze for two. Virtually no street noise, although note that the people sleeping downstairs will hear every step that someone takes upstairs ;)
Kitchen was small, but decently well equipped (coffee pods appreciated!) and we opted to do breakfast every morning in the apartment. The patio is charming, but given that it doesn't get direct sunlight and the cool evenings/mornings, we unfortunately didn't make use of it. Luisa and I communicated in advance of check in via WhatsApp and she met us with the key no problem.
Only word of caution is around parking -- prior guests has noted they parked their rental cars on the street, but the city has changed the rules and street parking is only for residents. Lusia suggested we park at a nearby covered parking lot and noted that it was a 5 min walk away and cheap. It turned out to be 30 euros a day -- perhaps that's the norm in Porto, but that didn't qualify as cheap by my reckoning! If you are coming with a car, either factor in that expense or find an apartment that includes a parking spot.
