I had a very nice stay at Aline and Igor. They are very kind hosts and will make sure you feel at home. The place is located just next to the boulevard, and you can see the ocean right from the garden. The garden itself is spacious, with plenty of room for lounge chair, a breakfast on stone table, and a pool. Do not forget to try out the Warm pool:]
For biking people, there is a nice flat bike path that goes until the south of Porto.
Arriving with a local train is also super easy and cheap, and the place is within walking distance from the station.
Thank you for hosting me :)
