We had a great stay at Elettras place. Handover of the keys worked perfectly, she even provided a basic stock of cereals, croissants, milk and cookies for breakfast. The apartment itself was very spacious, quite comfortable for 4 persons (2 bedrooms). Bathroom and toilet was a bit smaller, but still fine.
The neighborhood is really nice, just 2 blocks from the Colosseum. There are a few nice little restaurants nearby and also a Carrefour Express. Gay Street is also only a few blocks away, which means that the area has quite an open and liberal atmosphere.
It might be helpful to know that it can get a bit louder on the streets at night, which makes it hard to sleep with open windows.
