This place is exceptionally great!
First of all, Goncalo is very welcoming and helpful, many thanks to him for providing such great home!
2 bedrooms, 2 baths, dining area with projector (ideal for Netflix after long day), kitchen amenities, etc.
Above all, Carcavelos is located very well. 25min by train/15min by car to Lisbon, 15min by train to Cascais (or you can be crazy as I was - just walk for 2h from Cascais to Carcavelos along ocean).
Local beach is 5 min walking, really good if you are into surfing. Train station is 10min walk also.
