Staying at Mario's appartment was a great experience, easy to find on arrival, got all the neccesary information on time. Studio is as cute as seen at photos, perfect for a single traveller. Even the Port wine as a welcome gift was there :) thank you! Clean, cosy, super comfortable, with a lot of equipment. Location was perfect, I wouldn't pick better one if I knew Porto previously, which I haven't, close to the train and metro stations and many attractions. Mario is a great host, gave me all the information about Porto, special thanks for the restaurant recommendations :) We met several times and he was truly helpfull.
