We had a fantastic stay with Michele! (Unfortunately, Arianna was not there).
Michele welcome us warmly. He was very kind and helpful - willing to answer any questions we had about Rome.
The apartment itself is beautifully designed, very clean and fully equipped (strong wifi connection too). It is in a great location - a walking distance from bars, restaurants and shops. We found a taxi rank just a few minutes along the main road. From there to the train station, Colosseum, Forum and even Vatican City was all under 15€ via taxi.
Highly recommended and would definitely stay again!
