Steep stairs is going to limit access for some people who will need to carry luggage as no elevator. 2 floor unit is great for separation of living/sleeping quarters but living/kitchen room is only heated by an electric fan heater which is not the greatest. Bedroom level has built in AC/Heating units and is toasty warm but there's no seating upstairs, a strange decision by a builder/owner. Otherwise great Alfama apartment, great host.
