Sofia was a great host, the place is just as described simple, the shower could be better, but overall great place for my trip alone in Lisbon for one week, I worked from the apartment and had no issues with the wifi. Bairro Alto is a loud place by itself so no surprises with some noise at night, the stair was a challenge since I had large and heavy bags, but nothing exclusive to Sofias place, most older buildings there will have tiring stairs and no elevators. Again great stay to experience Lisbon while working remotely.
