We had a really nice stay at Lurdes and her husbands house. Her husband welcomed us with Port wine and cookies and told us a lot about the city. The room was super clean and really big. They live in a big old house in a nice neighbourhood. It's a 15 minutes walking distance to the city center. Communication with Lurdes was very easy and we had some conversations with both of them during our stay.
I would stay there again and highly recommend it!
