I have never met Mario personally. He was a very friendly and helpful host, who was always available. We arrived late in Porto, Marco managet that we got the key and into the flat. The apartment was very nice, bright, and with modern furnishings. There was coffee and tea-thanks for that! The small kitchen can be used well and the bathroom was big enough. the apartment is very close to the center. Little walks and you have a supermarket, metro stations and restaurants. The one problem we had, is that the flat sourrounded from restaurants. Son on weekends it's very noise. sometimes till 6 o'clock in the morning. Who needs to sleep should look for another accommodation. For guests who like to celebrate themselves long the apartment is optimal. Thanks Marco for the nice place to stay!
