I stayed at Nelson's place a few days in June and just loved. The house offered everything needed for your comfort and is located in teh best part of Azenhas do Mar, that is, in the middle of other fisherman houses. If you have a car, much better, because this way you can easily go to Sintra, Cabo da Roca, etc. I didnt and I still enjoyed my time there; the place is just magic and ideal to disconnect from work and connect with nature. I took a lot of long walks to nearby beaches, took a bodyboard class with a nearby school. The closest beach is 2 minutes away walking :)
Nelson and Elsa were fantastic hosts and helped getting to the house and took me to Sintra station. I highly recommend this place and I hope to be back soon!
