Cinzia is an amazing host! She stayed in constant contact from the days leading up to our arrival, then greeted us at the front door and helped us carry luggage up the stairs. She had 2 bottles of water in the fridge for us, as Rome gets very hot in the summer, and even left us pastries for breakfast. We couldn't have been more pleased with her as a host.
The apartment is fantastic, it has everything you could want including a fully stocked kitchen, spacious living room, dining area, extra linens, towels, toiletries, HDTV's, extremely fast internet (I ran an Amazon Fire TV with no buffering, laptop and 2 phones simultaneously), easy to use washing machine, comfortable king size bed, strong air conditioners and probably more great stuff that I'm forgetting.
If you're an American worried about traveling abroad you should pick this apartment. The French embassy and French consulate are both within 2 blocks. There is always armed Italian Military across from these buildings with armored vehicles. The area is centrally located and there is an amazing market down stairs for all types of shopping. There are plenty of restaurants and cafes to chose from making it hard to leave Campo de' Fiori everyday. Within a 4 minute walk, you'll find the Tiber River on one side and the bus stop on the other to take you all over the city.
If you're coming from the airport your best bet is to go upstairs and buy a train ticket to "Roma Termini" for 14 Euros per person on the Leonardo Express. Once you've arrived at Roma Termini, you can find a news/ magazine stand to purchase a bus and train pass. We stayed for 6 days, so we purchased a 7-day bus and train pass for 24 Euros per person. We took the 492 to the Rinascimento stop. From there it's a 4 minute walk from the apartment. If you're from the US, I definitely recommend exchanging currency before you arrive to Rome. They wanted to give me 65 euros for $100 USD while the rate was .90 to 1 (meaning they take about $25 per $100 to exchange!)
I can't say enough about Cinzia and this apartment, I've stayed at more than 10 Airbnb's thus far and this was definitely the best one. Don't pass this place up, it's a value and memorable experience all rolled into 1 great home.
