Joana was really nice, she gave us a lot of tips about restaurants and things to see in Porto! The apartment was just like the pictures describe it, very cozy and luminous. It was not cold at all thanks to the electric heaters, and during the night we could totally close the window shutters to be in the dark.
The only problem is that the windows don't isolate the house from the noises of the street (people + seagulls) so it can be quite annoying especially when it's very late at night and very early in the morning (the building next door was under renovation).
The house was well situated and at a walking distance from the city center.
The breakfast was delicious! don't forget to try torradas com manteiga in her mum's little bakery!
