Mario was nice to wait late for our arrival. Cozy studio with great location. Wonderful to see Clerigos clock tower right outside the window. Quiet enough to sleep comfortably. The bed was amazingly comfortable and the entire studio was very clean, modern, close quarters but cozy. Split bottle of port was a nice welcome gift and Mario showed all main sights and a few of his favorite restaurants which was great (Ze Bota has an awesome pork shank). Bathroom was nice with plenty of hot water. No elevator makes for the stairs to be a nice workout (should be used to all the Porto hills anyway). Thank you Mario, we hope to stay again!
