Mario made us feel welcome despite our delayed arrival. He answered all our emailed questions before our holiday and was most helpful while we were in Porto, giving us all the information we needed about public transport, visiting the main sites of the town and eating the specialities. The description of the accommodation was 100% accurate. The studio is very well located, within walking distance of many landmarks. It is small but well designed and spotlessly clean. The only negative experience was our last night (Friday to Saturday) when we experienced high noise levels from one of the nearby streets.
