I stayed for a few nights in carcavelos and Goncalo's appartment with some friends. We really liked the apartment. Its clean, has two bedrooms with nice beds, two bathrooms and sufficient space to live, work and celebrate vacation. We also really liked being close to the beach (5 min walk maximum). Carcavelos beach has a nice vibe, really laid back and good for surfing. Also close to Lisbon, Sintra and many other nice places that are worth visiting. Goncalo has been a great host, welcoming us by arrival and always happy to help us with other things (e.g. getting a PCR / covid test when that was suddenly needed). Would def reccomend staying at his place if you look for a not too busy place with relaxed vibe close to lisbon!
