The apartment is well decorated and spacious, we found everything we needed including dishwasher and washer and also coffee, tea, sugar and other essentials.
We all enjoyed our stay, the gelateria downstairs is excellent and there are enough restaurants and patisseries in the local area to chose from, although, not being in the centre of Rome some Italian is useful when ordering meals etc., however, we did manage with a phrase book and Google translate and everyone was willing to help as much as possible.
I would allow a good 25 to 30 minutes to walk to the colosseum unless you know exactly where you’re going and a travel pass for buses and metro is definitely a good idea to visit others areas.
