We went to Porto for a writing and holiday retreat. Sandro's flat was great. It is located near a metro stop and you can reach the centre and the beach easily. The flat is spacious and clam. Supermarkets and cafes are around the corner. Although we did not meet Sandro, he was a good host and all went smoothly. Intially there were some issues with the internet which he sorted out immediately. I can only highly recommend staying at Sandro's!
