It is very close to the collessium and has many restaurants around it. Major places in Rome are within 20 minutes, therefore you don't need to consider transportation. The building is a classical old one but very nice design of the apartment. The host Cecilia is very kind and we found the place more than we expected. She has a very good taste for decoration. She was very kind to solve the problem when we had wifi problem although she was out of the town.
I would strongly recommend her apartment for Rome.
