Perfect place!!!!
First, the hosts ( Nuno & his father) are very responsible and polite, on th e desk they left us things to do, where to eat and what to visit in Porto( because i was there only one day it was real saver for me).
Also Nuno respond on messages in a minute.
The apartment.
Location is WONDERFUL, everything that you need is 5 min walk max, its in quiet neighborhood in the centre, you can enjoy Porto by foot.
The apartment is PERFECT, it is like your home far away from home.
Its sparkling clean and the beds are more than comfortable, also they have everything that you need ( hairdryer, clean towels), and the details in the apartment... amazing.
I definitely recommend this apartment and for sure I'm coming back here again.
