Wonderful Airbnb for large groups! Spacious, each bedroom with ensuite bathroom, sunshine on the terrace, right next to a bouldering gym (which you can enter free as airbnb guests). It's located ~10 mins by car from both the airport and Lisbon centre in an industrial area, making it very private as you have no neighbours. The hosts were also very responsive and helpful. We went with a group of 15 and had an amazing time. We came mid-January and the space was also warm enough as each room had an AC/heating unit. Would definitely come again.
