I don't think I've ever had such a perfectly located Airbnb. Immediately downstairs is Campo Di Fiori, one of the popular spots in Rome, and you have access to pretty much anything - restaurants, bars, shops, markets, etc. It was crazy how close we were so going out for dinner or out for a drink didn't require a lengthy walk back to the place. You definitely don't need to use a taxi around the area - even walking over to the Vatican didn't take more than 30 minutes or so. Rome is a very walkable city and this apartment was centrally located. Keep in mind it is a 4th floor walk up, but after eating yourself silly with pasta- the exercise was welcome ;)
The owner was wonderful and even arranged for us to be picked up at the airport (for an extra fee, but very reasonable and worth it over any taxi) by a private driver, which was an excellent service and the driver gave us a bunch of tips about Rome and places to do, things to eat, etc. The owner was very open with communication during our whole trip and made sure we had everything we needed. The apartment was very very clean and had fresh towels, toiletries, coffee, outlet adaptors (yay!) etc for us to use. They even have a lockable safe for you to store your valuables, which was a nice addition.
Great service and great apartment. If you want to see the sights of Rome and be in a bustling, young area - then this is the place for you!
