The flat is located in the Vila de Nova Gaia, around 10-15 mins on foot from the Ponte Luis I which makes it easy to quickly reach the Porto's city center. In the apartments area there are several cafe's and bars, which are cheaper than those in Porto. The neighbourhood is rather quiet.
The apartament itself is well-equipped, there's a kitchen with all needed utensils and a washer. The space is rather small but enough. The walls are thin - it wasn't a problem a problem during our stay, but have that in mind.
The biggest "+" of the apartment is the host - Danilo. He was very welcoming, happy to answer any question we had and gave as a lot of handy tips both about the city and Portugal!
