Great stay at Mario's apartment. Location is right outside metro stop, so journey to and from the airport is very easy. Near to main high street with lots of shops, restaurants and cafes, plus easy walking distance to other areas filled with bars and restaurants. Excellent base for exploring Porto's sights and can walk to all from the apartment with the river around a 10-15 minute walk away through nice streets and past many sights. Check in was easy and Mario on hand when needed. Apartment clean, tidy and spacious. Great value stay, would recommend.
