Sérgio was a great host. We arrived earlier than check-in, but he kindly held our luggage in his own apartment. When we then met him later on, he gave suggestions for places to go, and even drive us around the area of Belém. The apartment itself was gorgeous; very clean and the perfect amount of space for the two of us. It was very close to regular buses, a tram, and a few minutes walk from the train. Ideal if you want to be in a quieter part of Lisbon and don't mind public transport and/or walking. Thanks for everything Sérgio :)
