The place is located near a metro station and a large shopping mall (clothes, groceries, food: restaurants, fast-food), which makes it a great convinient location. There are also night-buses from Porto to a nearby bus-stop such that you do not have spend money on taxi if you want to stay after-metro-hours.
Although you share the house with other guests, you have a lot of privacy: your private bathroom, kitchen, and small terrace.
The host is nice and shares a lot of nice tips about Porto and surroundings, there are also maps and brochures available at the house.
One thing to take into consideration: there are construction works nearby (in Aug 2018 there were) so if you are a noice-sensitive-sleeper, it is better to take ear-plugs.
Overall, we had a great stay there and we recommend the place and the host.
