Jaime, his wife and daughter are very nice and offer help whenever needed. The rooms are very big, like there's lots of free, unused space. Unfortunately we couldn't open the windows to let fresh air in. As far as I can tell there are 3 rooms in the building that they rent and 2 shared bathrooms outside of the rooms - ours had 1 shower and one toilet. The bed (king-sized) was comfy, but the blankets where not covered in bed sheets, which I'm used to. We had a fridge in our room and a big kitchen you can use but no breakfast included.
Espinho (the town) itself doesn't offer much except that its waves are great for surfing, but there's also a train that takes you to the center of Porto within 30 min for just 2€.
