I loved staying at Luca's place, I was a single traveler and I felt completely safe there. It's well located near Termini Central Station, you can walk there as soon as you arrive in the station. All the touristic attractions are a close walking distance, although you can also take the metro. I walked everywhere I went, except when I went to the Vatican, but all I had to do for that was jump on the metro and I was there in 30 minutes (he provides free city/metro maps) Luca's place is very clean and I had my own bath room, everything worked great, he even provided yogurt and juices for me in the morning so I wouldn't head out on an empty stomach, there was also coffee and tea. The internet worked great I had no problems with it, the bed was comfortable. Luca was very hospitable and I most definitely reccomend his place, next time I go to Rome this is where I'm staying.
