This place has an unbeatable location at the heart of the famous Alfama neighborhood. We got there from the airport using two metros and the tram 28, but an Uber can get you to "Miradouro de Santa Luzia" where you can take St. Luzia elevador to get to the apartment door. This information is crucial specially if you have a big luggage since Lisbon's pavement in our experience is not luggage-wheel-friendly :) The apartment is also close to the Tagus and São Jorge Castle (500 m)! Just have in mind that similar to most other apartments in the neighborhood you should expect very steep steps to the door step; i.e. 3rd floor with 45 steps at 40+ angle. So not not-used-to-elderly-friendly.
Same as other comments the place was sparkling clean and we had support of the host. First night the rooms were cold but we got sensible instructions to make it comfy after a while. We highly appreciated the offered late checkout that saved us the extra efforts of the last day.
Many thanks and keep up the great work guys!
