Marta is very welcoming, just a lovely person. My boyfriend and I arrived way before official check-in time and she was very accomodating and flexible! The house has a homely touch and there were even two citron and orange trees in the garden which we could harvest from. Although it was a bit cold in the house, the heaters kept us warm :) There is a wide range of breakfast options available, so everyone will find something they like.
One thing I particularly liked about the room was the desk and chair in front of the window - I had to finish some assignments and this was the perfect work station for my laptop. The location is not in Porto downtown, and it's about a 30 min walk to the beach but the metro station is only a 7 min walk away, so you get to the city quickly nonetheless!
