We stayed 3 nights in Henrique's house in Porto. It really looks like on the pictures: the house is very nice, in a quiet area, with safe and free parking places just in front. Henrique's wife was very welcoming on our arrival, giving us lots of information, + a bottle of Porto Wine !
Only drawback: it is a bit far (by foot) from the city center.
All in all, we would give 4,5 stars to this house !!!!
