Luca was a fantastic host! He was very welcoming and we felt like we could contact him at any time for anything we needed. He provided us with a map and list of restaurants to eat at (which were fantastic!) He also gave us a bottle of wine to welcome us.
The apartment itself is just like the pictures and the bed is comfortable. The location could not be better. There are so many bars and restaurants within 5 minutes walking. It was also walking distance to many of the tourist sites, maybe around 20-30 minutes. And if you wanted to take a taxi (we were lazy at times...), there is a taxi stand only a block away. A taxi from a major tourist site back to the apartment was typically a little less than 10 euros. We used the private rides to and from the airport that Luca set up for us, which is the same price as a taxi (48 euros), and that was a fantastic choice.
It does stay busy around the neighborhood until around 1 or 2am. We usually slept in and stayed up late anyway, but Luca provided earplugs if needed, we never needed to use them. We would definitely stay at Luca's place again if we are ever in Rome!
