I would highly recommend staying with Lorenzo if you are looking for nice comfortable conveniently located space for a reasonable price.
Lorenzo was a fantastic host from the very beginning of the booking process. Communication was fast and seamless. Lorenzo was able to arrange for private pick up to and from the airport. This was very convenient as taxi cabs in Rome are small and able to only fit three passengers. We were picked up in a large Mercedes sprinter van for the arrival and on the departure, we had a Mercedes sedan. I had great peace of mind not having to bother fetching a cab from the cab stand. The price difference was only 12 euros. If you use the car service, check-in is seamless and there was someone there to show us the amenities of the apartment upon arrival.
The location of the apartment was fantastic. It is one minute from the bus station and metro station and overlooks the colosseum. The location was at most 20 minutes from most locations in Rome by foot. The neighborhood is cute and very safe, perhaps the safest building in Rome as it is monitored by armed guards since the Defense Minister lives in the same building.
As for the apartment itself, it is very clean and has all the amenities you would want for a stay in Rome. There were plenty of towels and Lorenzo was kind enough to stock the bathroom with shampoo and soap. A fantastic touch.
I will surely stay with Lorenzo again if the apartment is available. Ciao e grazie mille.
