We were a group of 3 and we stayed in this flat for 11 nights. I only have positive things to say about it: recently refurbished, well equipped kitchen, large and comfortable living room and bedrooms, charming balcony. It can easily fit four people. It also has a large desk in the living room that's perfect if you are working from home. Location is great if you wanna stay close to the beautiful Carcavelos and Torre beaches. The main touristic sights of Lisbon are far but easily accessible by train. Sofia and Luiz are great hosts and they solved a small problem in one of the bahtrooms super fast. Definitely recommend it!
