I would 100% recommend to stay at Carlos's place!! We were only meant to stay for 4 nights but extended to a week as we enjoyed it so much! The tent is very comfortable with a blow up mattress and plenty of space in the stand up porch for your stuff. The kitchen Carlos has built is fully stocked with your own toilet and shower to use next door. The swimming pool is amazing after a day's walking in Sintra, which is not far to get to - a 10 minute walk to the bus stop then about half hour on the bus and one train stop or another 20 mins walking the other end. The town of Janas has 2 shops selling many organic and vegan goods, a couple restaurants and a nice coffee shop. Carlos, Raquel and their kids are the nicest family ever! Helped out with everything - tips on where to go and transport, always there to help, I even got a tour of their much loved chickens big patch of land and they gave us some of their lemons when we were feeling unwell - we literally felt like part of the family.
Carlos and family, we cannot thank you enough!!
