I highly recommend staying with Luis. He is a delightful host. Luis offered to pick us up from the airport at 11.30pm but stayed and waited for us when we were delayed an hour. His home is equipped for travellers and he makes you feel very much at home, offering breakfast and coffee and access to basically anything in the kitchen. He is very good to keep in contact with, always on hand for advice or help if a fuse blows. Luis is funny and charming and puts in a lot of effort for his guests. Getting into Porto is about a 10-15 minute drive and there is a supermarket around the corner too. Highly recommend!
