Tony’s apartment is a cute little spot in Alfama (an old, mainly pedestrianised part of the city - think winding, cobbled streets up/down the hills).
The apartment itself is up a narrow and steep set of stairs (not a problem if you’re fit, just worth bearing in mind) and is well equipped if you want to cook/have a quiet evening in the apartment. It also has a great view over the city and the river - just bear in mind, you can hear the PA systems from the cruise ships docked on the river.
All in all, a great place from which to explore the city!
