The apartment is very well situated in the heart of Rome. We did most of our trip by foot. The drawback of this situation is the noise at night. There are several bars in the street which is great but the people coming home in the middle of the night can be noisy. Make sure to take earplugs with you. The contacts with Simona were easy and she made sure that we had all we needed for our stay. It was a great experiment. Another tip if you plan to visit Vatican is to pre-order your guided tour on the internet. We skipped all the lines :-)
