Alfama is a fascinating and amazing part of Lisbon - truly unique in character. Be prepared to walk down alleyways and tiny laneways in a giant maze - such a good part of it all. Learning to think you're lost each time but get to where you want is also a great experience. We stayed for 5 nights and it was a good amount of time to get to glimpse the place.
The apartment is in a great location and we thoroughly enjoyed our stay.
