This apartment is the perfect location if you're looking to explore Rome. Everything is well within walking distance. There's also a major bus stop and taxi stand right around the corner from the apartment.
The apartment itself is lovely as well. It is spacious, clean and very comfortable. I could not have asked for a better stay in Rome!
If you are traveling from the airport, I recommend taking Claudia up on the offer to set up a car pickup. It's a good price (50 Euro total) and the driver knows the apartment and will take you right up to the front door.
