We had a lovely time in Carcavelos. The flat was a little bit hard to find at first but once we got there Catarina's parents gave us a very warm welcome. Even though there was a language barrier we managed alright. There are grocery shops and cafes in the area and the beach is not far. Not much traffic nearby and basically quiet. Since the balcony is closed, it is not letting in a lot of summer light, but on the other hand that makes the apartment nice and cool also on a hot day. We can highly recommend the place and its proximity to beach and also Lisbon.
