We stayed at Marcos for a 3 nights and I think this flat is great value for money. The location is perfect, only 10 minutes walk to the metro that goes to the airport. Also, there is a supermarket next door, a great burger place downstairs that do take-away as well and the best "francesinhas" in Porto are served just across the square. Even being so centrally located the flat is very quiet as it faces the backyard. It is an old, charming building and the flat has very high ceilings. Traveling in December we thought it might get a bit cold, but we had 4 electric ovens in the flat that kept it warm and cosy. Everything was very clean, and the kitchen was well equipped. We were met by Marcos mother-in-law and she was so nice and gave us good advice for what to see in Porto. I also want to stress the flexibility around check-in and check-out. We got in before 3 pm and as no guests were arriving the day we left we could stay longer than 12, and that we appreciated a lot. Thanks for a great stay! I would recommend this flat any time.
