As is promised by the very name of Maison Elettra Colosseo - the apartment is 2-3 minutes walk from the Colosseum (5-8 from the Metro station).
It has two bedrooms (one rather spacious), a nice living room and a cosy kitchen.
In our case, it hosted nicely a family of 4.

Elettra was nice and helpful. She handed over the apartment neat and clean, and stacked it with some basic food to get us started. The neighborhood has two supermarkets and a whole host of places to snack, eat and dine.

I and when I find myself in the neighborhood again, I shall certainly look up this place again.
