We had a great time in Carcavelos, Paulo is very welcoming and the apartment is amazing : 5 min from the beach for chilling and surfing and 20 min to Lisbonne and Cascais. Every commodities you need is right here : a grocery store, a pharmacy, a cash machine and a pool !
Th place is big and very clean, with a balcony, we don't miss anything.
I will definitely recommend this location !
