We had a great stay at sofias place. We spend 8 days with our 4 yr old boy and 8 months old girl. We mostly spend the early mornings in and around the house. The sun in the yard outside is very nice. From noon there is no sun anymore which makes the yard too chilly to stay during this period of the year (march). Also staying inside wasnt the best option as the air humidity is high. Offcourse there is a plethora of things to do in sintra so that wasnt a real issue. At night we did stay inside. The dehumidifier worked well but the air stays a bit thick. Nevertheless the lounge corner is a cosy place to chill out from the busy day.
Overall i would recommend this place for sure.
