The appartment is perfectly located near the Vatican and the center of Rome. A supermarket and several restaurants are nearby. You can reach everything by foot and do not even need to take the bus if you do not want to.
The appartment is small but perfect for two people. The balcony with the view on the Cathedral is incredible. The parking is directly at the building and gated.
Catharine and her team could be reached anytime and have been very helpful and friendly (advises for our Rome visit, breakfast, ...).
