The location is amazing for someone who is after historic sites and sightseeing.
The place is perfect for a couple who want to walk around alfama or get to the 28 tram which stops 2 minutes away from the flat.
Good restaurants around as well.
I would not recommend Alfama for parents with little kids in baby stroller as there’s too many hills and stairs around the area and the stairs to the flat are very narrow.
Mind that in Alfama (in this area) you’ll have to be quiet from to 11pm to 7am
