Staying at Irene's place was a great experience. Her instructions were clear and precise, she is always ready to answer your questions, and she even took a walk through the neighborhood with me when I arrived showing me what's what.
The apartment itself looks even better live than in the photos, it's spacious and clean, situated in a lively neighborhood but very quiet and connected to the center of the city with a few bus and tram lines. The only thing you have to be aware is to be careful when using the shower, since it is a bit on the smaller side. Nevertheless, a fantastic value for money.
Since it was a relatively short stay, I think it is a matter of time before I return to Rome, and I also expect I'll stay at Irene's place again.
