I've used AirBnB quite a few times now and can say my experience with Pedro was one of the best. Great communication. Friendly, honest and down to earth person. His home is beautiful and in the heart of Alfama (the city's only pedestrian streets). It's clean, charming and perfect for anyone who wants an authentic, local experience. Bonus: Elevator in front of flat for easy luggage transport. Tons of cute restaurants, shops and "pop up" bars only a few steps away. Pedro and his brother Hugo both provided me with an unforgettable experience. I won't stay anywhere else next time I'm in Lisbon. :-)
