Miguel is an excellent host. He was very welcoming and he gave us a lot of good tips about the city.
The communication with him was extremely easy and his place is perfect: not only in an excellent location (6 minutes from the tube and 20 from the river), but also spotless.
The apartment is nice and well equipped (in the kitchen you'll also find the basic stuff to cook such as oil salt which is a plus).
I would definitely reccomend him as a host and if I'll have the chance to visit Porto again I will book this place again!
