Most places are meant to stay overnight. In this apartment you want to live :)
It is just as bright, spacious and cozy as it looks on the pictures. It has a kettle, toster,hair drier and almost any other thing you might need. We even found a jar of Nutella in a cupboard!
Luis is a very nice guy and a great host. He was always in contact when we needed his help. On our first day we arrived a bit earlier than we expected, but Luis organized everything really fast so we almost didn't have to wait to get to the apartment.
The area is nice and quiet. To get to the city center use buses 701, 702 or 703 that go from the bus stop near the house. It's only 15 minutes ride.
I recommend this place to anyone who's looking for a nice and comfortable place to stay in Porto.
