Samuel's place is great. We stayed in Bica in the 2 bed apartment which fit 4 of us comfortably - the living room and kitchen are very spacious. The location couldn't be better for access to restaurants, bars and the nearest metro station which is around 5 minutes walking. If you like an early night it may not be ideal as it is situated on a street that is noisy at night, but we loved being in the centre of the action! There is a French bar downstairs with a very friendly barman. Lisbon is a fantastic city and I would highly recommend Samuel as a great host.
