Finally I have the time to leave a review, dear Adérito.
It was my first experience as guest and not host and I have to say that it was GREAT! From the beginning until the end. The apartment is located right in the center of Porto and it has all the possible things you need (washing machine, dishwasher, coffee machine, cable TV, high speed Wi-Fi). The communication was great, the check in and check out perfectly on time and Adérito is super kind, he gave us all the possible tips we needed. In the end, it was a 5 stars experience. Totally recommended. I'm sure you will be a Super Host in no time ;)
