Very good accommodation! We didn't meet The owners, but Theresa was there the whole time and really was a great host to us. Best breakfast we had at an Airbnb. If we go back to Sintra I won't think twice about booking here again. Very clean, very nice, everything in good working order, great wifi, absolutely no complaints. Can't say enough good things.
Note: best if you are travelling by car, it's approx 15-20min drive to sintra based on traffic
