Me and my girlfriend loved our stay in Lorenzo's apartment. Lorenzo was very prompt in responding to my texts/emails and was there to meet us once we'd arrived.
The location is great - lots of nice shops and restaurants nearby, close to the metro, and about 5 mins walk to the Colosseum.
Inside didn't let down either - extremely clean, modern, and comfy. Lorenzo had stocked the apartment with croissants and juice which was a nice touch.

It's a compact apartment, perfect for 1-2 people. If that's what you're looking for, I fully recommend Lorenzo's apartment. We'll be coming back!
