The appartment is nice and very well placed, there are nice restaurants and supermarkes nearby. It's a 10 minutes walk to the beach and right in between Guincho and Carcavelos beaches. We were only able to talk to the host by messages, but she seems nice too.
Cons: We encountered the flat completely dirty except the bed clothings and towels and we had to wait 40 minutes and rescheldule the arrival due to miscommunication and technical problems on the part of the host. This problems seemed fortuitous though.
