The apartment itself is big and we enjoyed having breakfast in the kitchen and being able to use the space to prepare lunch to take with us.
You do need to change metros once to get to termini and twice to get to Colosseo, but the apartment is very close to its metro stop and right near a great little street with lots of restaurants and bars with fun LGBT+ friendly spaces. Really the best of both worlds, because you can spend all day in the city and have a really great, lively place to eat dinner at that is cheaper than eating somewhere in the city.
