I highly recommend this apartment and the very kind hosts!
We stayed for 9 nights (work and holidays) and felt very privileged to stay in this area of porto, where everything is just around the corner. The apartment offered everything I was looking for... so I also prepared some meals for us with the beautiful vegetables I bought just near by. Whenever we went out with locals, they took us to very nice places in our neighbourhood, so we had only a few minutes to walk home.
You can watch and hear the street life from the balcony, but if you close the windows, you won't be disturbed at all.
The hosts have been always very nice and helpful, recommended places that really matched our interests and made sure, that we could always ask for help. After one week we even got a total cleaning of the apartment.
We really enjoyed our trip und would love to come back one day to stay at ana's and her son's.
