I was in Sintra with my sister Michelle at Carlos' Airbnb for two nights, and all we can say is how wonderful it was. We went by public transportation and the connections to and from can be a bit difficult, so that is something to be aware of. However, Carlos answered phone calls and texts super fast and was very helpful, so any issues were addressed very quickly. Once we got there, he showed us the tent and inside was a small portable table with towels and a little guide to Sintra (with the attractions and bus timetables) and his suggestions. Then he showed us the grounds, complete with a very well equipped kitchen and bathroom with a shower. Wifi is accessible everywhere on the property. The tents are super cosy and cute! Once you get in the sleeping bag that is provided, along with an extra blanket if needed, it is very warm inside and my sister and I slept wonderfully.
Along with how well equipped and comfortable we were, the hospitality really gave the place a community feeling. The other campers helped to complete this great experience that was provided. It was truly a very positive experience. We can definitely recommend 100% and hope to stay again one day.
