Barbara is fantastic and great with communication before and during your stay. The apartment is just as it seems online and in the pictures; it was very roomy and having three bathrooms was fantastic for the number of people we had staying. We had an issue with one of the faucets and Barbara had it fixed within hours, before returned to the apartment.
The apartment is very close to the Metro (2 minute walk) and the Vatican (~10 minute walk) so is in a great spot which is pretty quiet as well.
I would highly recommend this apartment for anybody looking to stay near the Vatican, and look forward to returning myself.
