This apartment is in a great location, about 10 minute walk from the Colosseum and Foro Romano. There are a few good restaurants around, as well as a supermarket (with a lovely patisserie place next to it where we would pick up our breakfast). The train station Termini is about 20-25 minute walk away, or there is a subway station (Manzoni) about 10 minutes away which can take you there too if you are carrying loads of bags.
The apartment is at the bottom of the building, you only have to walk up 5 small steps. There is a kitchen area (which we didn't use as we ate out), a big bedroom with storage space and a lovely bathroom with shower.
Maddalena gave us helpful tips of what was around us, including tips on where to find the supermarket and a local restaurant. We were also allowed to check out later on our last day due to a late flight, though of course this is something you would have to check with her to see if this is possible.
We had a great stay in Rome and really enjoyed the apartment. We would stay again if we decide to visit the city again. :)
