First off, Manuela is a very kind person and just great to communicate with in general. She wants to be helpful and her friendliness would be greatly appreciated for a family that has never been to Rome/Vatican before. She is willing to coordinate rides to and from the airport and she makes GREAT restaurant recommendations.
The space is great for cooking and there are places close by to buy groceries.
I will absolutely consider staying here again the next time I come to Rome/Vatican.
The only couple things to note:
1) There is a sort of busy street nearby so if you are a light sleeper, ear plugs would be a good thing to bring. I used mine the entire stay.
2) The shower might be difficult for an older person or someone that is larger. The step to get into the shower is pretty high and can be slippery.
Thanks Manuela!
