Mirko and Elis were fantastic hosts who go above and beyond to deliver a first class guesthouse service. They were always on hand for questions and provided lots of info about the apartment and Porto. The apartment is spotless and the room is perfectly comfy, quiet and good for working from. The WiFi in general was good for work, though it did cut out one evening for 20 minutes while I was working. Location is good too, just a 20 min walk or so into the old city and just 10 mins or so from the nearest metro. The breakfast is a great way to start the day with a really good selection of food for every taste. Overall, an excellent choice for anyone coming to Porto for a few days. Beautiful city and a very safe and welcoming place to stay. Obrigado Mirko and Elis!
