First and foremost, Antonella was wonderful - she arranged a taxi to pick us up from the airport and also one to drop us off after our stay.
However the best thing about our stay was the location. The name "100 steps to the pantheon" is accurate. Couldn't have asked for a better location - everything you would want to see was walking distance, with the apartment being right smack in the heart of Rome. Another great thing about the neighborhood was there were at least four or five restaurants right downstairs. We tried two of them, and they were both fantastic. It was very convenient having such great food a stones throw away.
The place it self was also wonderful. Very cute and quaint, as the older building added a wonderful character and perfect backdrop to our roman adventure.
The only things I would keep in mind is that it's situated on the third level with no elevators, so if you have trouble carrying heavy suitcases or have a great deal of trouble climbing stairs you may need to take that into consideration. However it's really not that bad of a climb, Antonella is more then willing to help with the bags, and is a minor payoff to living in such a beautiful and historical setting. It really felt like we were in Italy. We loved it!
