As almost all previous reviews reflect, this is an incredible apartment. It is in an area of Rome that is close enough to the tourist attractions that you can walk but if you are within the immediate surroundings, you will find mainly locals. The restaurants are good and the people are more genuine than in the highly trafficked tourist areas.
The apartment itself was perfect in every way for us. It was immaculately (even though not located in the Vatican area) clean and had all of the things that we needed for the week. Most importantly, the bed was very comfortable and it was eerily quiet the entire time.
Marco and his brother are the perfect hosts. They arranged for our transportation from the airport and spent plenty of time with us in acclimating us to the apartment and surroundings.
I strongly recommend this apartment to anyone who wants to experience Rome without the shoulder to shoulder throngs of people with which to contend as you walk out your front door. You will not be disappointed.
