Marzia met us on arrival and was very helpful with information on the area in which we were staying. She had also arranged for us to be picked up at the airport, which was such a luxury after our long flight. She was available by phone throughout our stay.
The apartment itself was on the 4th floor. There is an elevator, but you still have one flight on the ground floor and one flight on the 4th floor which you have to take. Just a warning for those impaired.
Campo Di Fiore is a very popular area, with a bustling market every day. Very exciting to be there in the middle of it all. The windows in the bedroom open out to this scene. Great during the day. At night this becomes a restaurant/bar scene. Be warned: there is noise. Music & revelry. Ear plugs worked for me for sleeping.
WiFi was weak, at best. However, the restaurant downstairs (La Carbonera - a good place to eat, btw) has a connection that works upstairs near the window. Weakly.
Although we didn't see her on our departure, Marzia also arranged for a cab for us to the train station. Again a big help. I would definitely recommend this place, as long a you know about the noise level and are prepared.
The host could not have been more accommodating.
