Liana’s reply is made so quickly.
Car park is also free, that is located from 3min. walk from the house. In general, Porto and Gaia close to Douro River have many slopes and narrow steps, so that handling suitcases would be much harder if you would have more than one suitcases by person. This house will be good for young backpackers.
Breakfast can be enjoyed in local shop/cafe nearby.
