Mario was the perfect host - very kind, helpful and open-minded! It was our first time travelling with AirBnB and he was always available and answered all our questions to the accomodation or the city. The apartmant is located right at the centre of Porto and Nata Lisboa (the café where you can get the inclusive breakfast) is just a few steps away. The bedroom, kitchen and bathroom were all clean, tidy and tastefully decorated. Mario also provides an App for smartphones where he marked special places in Porto, restaurants and cafès; the app also works offline, so you can use it as a map of the city as well. We were very, very happy with his apartment - he made our trip to Porto a unique one :)
