Mario was a very attentive host with good communication throughout our stay. He allowed us to store our bags on the last day which meant we did not have to drag our luggage around on the last day. We were left a gift of Porto in the form of a bottle of Port in the apartment for our arrival which was a nice touch. The apartment is very well located within walking distance of all of Porto's central landmarks and across the road from the railway station and metro. The bedroom is quiet at night when the shutters are closed. The balcony is a great place to sit and read with views of the Cathedral and Tower. Would recommend.
