We loved staying here! The apartment was clean and felt very safe. They had everything we needed, extra toilet paper, power converters, towels, etc.
One thing to keep in mind is that this place is extremely lose to the Vatican, but about a twenty minute walk from the nearest metro station.
The only things that could make this property ever so slightly better would be an extra set of keys (our group had two sets of couples and it would have been nice to have a set each in case we needed to split up) and a better organized information binder (the English section was not all together and I had to flip through a lot of pages to find all the different pages). These two things were not a negative to our stay here, and I highly recommend this place to anyone who comes to Rome!!
