This apartment is in the heart of the the oldest neighborhood in Lisbon full of insanely picturesque with winding narrow alleys and sidewalk stairs to the top of the hill. The location is great because it's very close to the main street, not too far up the hill.
Look for the Fado museum and then go up the street with the ATM for a couple of meters and then turn left up a narrow alley. If you stay here, you can check off a recommended activity of checking out the Alfama by simply going about your daily business
The charming apartment had every possible amenity one could imagine, was very clean, and Arnaldo was kind enough to arrange a very nice host to be present for our late arrival. Although our stay was brief, we felt really at home there. We also managed to lock ourselves out of the apartment(!), and Arnaldo had a locksmith out quickly to resolve the issue.
Another bonus is the restaurant literally below the apartment. Sandra speaks excellent English and was amazingly gracious, and Marta is really lovely. We ate all our breakfasts down there, and in our jetlagged state, the fresh squeezed orange juice and very generous omelets really hit the spot.
