For an apartment in central Rome, only 50 meters from the Vatican, this apartment cannot be faulted. It was clean, well-appointed and easily accommodated our family of 4 kids and 2 adults. We were met on arrival by the very helpful owners representative and didn't find a single thing wrong with the apartment. I thoroughly recommend it.
The only one minor complaint is parking - the info on the apartment says there is parking but this is public parking outside on the street and is not in any way dedicated to the apartment. Parking here, like anywhere else in Rome, is awful. Don't even think about using your car regularly and looking for a space each day. We parked ours in a Blue Line space (8 euro/day) and didn't move it for 4 days.
