Good location. In walking distance to the historic centre of Porto with a few good restaurants for breakfast/brunch on the way.
Communication was easy. We booked the place for 3 but only had 2 beds/bathrooms prepared, Rui/the team replied quickly and dropped of the missing bed linen on the same day, so no big deal.
Having 3 bathrooms, 1 on each floor was really convenient, especially when staying with friends. We did see a few spots of mold in the bathroom on the ground floor however. It could be just a tad more clean, e.g. left over hair from previous guests, but all in all it was OK.
