Luigi and his apartment were wonderful! Luigi was easy to keep in touch with and met us promptly at the apartment entrance upon arrival. It is on a busy street with lots of shopping and easy to find. Many restaurants and gelato shops are nearby as well. The apartment was clean and everything was as pictured. The bed was comfortable and the bathroom was the nicest we found in our three city tour of Europe. Plenty of hot water for two people to take quick showers. The kitchenette has dishes and pots so light cooking can be done. There's also a coffee machine, but I didn't know how to operate it, so I left it alone. The WiFi worked well, but my phone was buggy when connected to it, so I'm not sure if that was a side effect of Rome...
The metro stop is about a 7 minute walk and there are bus lines only 5 minutes away. We ate at Luigi's family restaurant (just around the corner) on our first night as well, and the food was great! I fell in love with white pizza that night. =)
Vatican City is practically next door (7 minutes walk) and is a must see when here. We also walked to the Spanish steps and quite a few piazzas and fountains. The Trastevere is a short bus ride away and offers great food and shopping from local artists. The area felt very safe at night, and was private with no noticeable noise.

Luigi offered to arrange a driver pick us up at the airport. The cost was 50 euros, and for two people to take the two trains into Rome it would have been around 30 euros, so the extra money was worth not having the hassle and taking up another hour of our time. It would have been and a lot of walking on rocky roads with our luggage and train changes at the Termini. Much less hassle this way. And when you leave the apartment, there is a taxi stand 2 short blocks away, flat fare to FCO is 48 euros.
