Maria is absolutely lovely and very hospitable - she made sure that I was comfortable and having a good stay. There were plenty of blankets and a space heater in the room - so I was very warm and comfy, even on cold nights! The space is very close to a nice restaurant for dinner and an easy walk into the historical centre of Sintra (about 10min). I found it easy to walk to all of the sights and had no problems at any point. Basically it's safe, convenient and comfortable - everything you could hope for!
I would really recommend staying here if you're planning on coming to Sintra.
Thanks for a lovely trip Maria!
