We had a lovely stay at Vasco and Márcia's flat. The flat look exactly like on the pictures. Everything is new, it's super clean and optimised. We absolutely loved it. The communication was also really easy, we could arrange easily for our arrival and departure with Márcia (who is lovely).
The flat is located a bit outside of the center but it's only 10 min walking (which is good to digest after a good portuguese meal). The only downside would be that the street is a bit noisy but otherwise, nothing to say. I really recommand staying there !
