Stefanias apartment is very centrally situated, 10 minutes from the vatican, 30 minutes from the coloseum and most other attractions, trevi fountain about 15 min. Walked every where and if you're reasonably fit no issues. The stairs up to the apartment were not an issue, narrow so awkward with luggage but its only and up and down once - 5 flights if i remember correctly. Apartment is perfect size, clean well equipped and everything you need. The top terrace has lovely views towards vatican and perfect for dinner. We were met by Alexandria who was enthusiastic and made a great effort to makes us feel well come and orientate us with all attractions and necessities. Great time
