Rita's apartment has plenty of space for anyone looking to stay. It's not too far from the city centre which is within walking distance and is also very accessible with an elevator in case you have any heavy luggage. The kitchen is also fully equipped if you choose to cook instead of eating out. Our flight was also delayed so we arrived later than planned. Michael was really helpful and waited for us so that we could still check in.
If you choose to stay here, I really recommend that you try having breakfast or lunch at the bakery next to the building (São Jorge Padaria e Pastelaria). We really loved eating there and the people are really friendly. We really enjoyed Porto in general. The vibe of the city and the warmth of the people were very welcoming. I would definitely consider staying here again if possible the next time I'm in the area :)
