Firstly, the communication was very welcoming and very fast! There are a lot of Ubers around the area so if you come by train you can get to the place with ease, even though it is a (semi) rural area. The welcome was great, the caravan is in great shape with everything you need. The place is quiet, and everyone keeps to themselves but at the same time it's secure.
Martin welcomed us warmly (also, on the table there was a bottle of local wine and some fresh produce from his gardens), and explained everything too us, all the intricacies and workings of the caravan, how the place is run, how to get your food, how to get around the area etc. (You're 10 mins walk from the nearest village where you can get all your shopping done).
He brought us to the beach and to Sintra, both only 10-15 mins by car. The nearby beaches are great, some more touristy than others depending on your interests. There's a small electric tram that runs from Sintra to Praia das Maçãs that has a stop close to Martin's place.
Overall, we had a great stay and felt genuinely welcome there. It's family friendly and has been a great experience for the kids They spent the time there reading and even helping out in the gardens and weren't bothered at all by not having a television, their minds relaxed into it immediately once we got there.
We recommend it without any doubts at all. One important reminder though to make sure the stay is even better, this is the country so pack some mosquito repellant. :)
Thanks a lot for everything Martin! We had a great time and you were a big part of it!
