The apartment is very central in Alfama, not far from the metro, buses and 28 tram (beware of the hills, of course). The living room has an amazing view on the river, unique. The bedroom has windows facing the narrow street with bars and restaurants, which is quite loud during evenings and nights (at least in August during the high tourist season), we slept in the living room, as it was hot weather and there was no A/C in the apartment, so we could not close windows.
Beware that Uber and other taxi services (except for the city taxi) cannot come to the building due to the restrictions, they stop in 100-150m from the entrance at the beginning of the street - not a big deal if you don't have much luggage.
Generally, the apartment is well suited for a short stay during vacation.
