The Onofrio Apt looks exactly like in the pictures. It's beautiful and feels very authentic! We loved everything about it: The location is perfect, the nights are quiet, the beds are comfortable, and since the appartment is underground, it keeps the place cool, which you will need when staying in Rome in the summer.
Sara was very easy to communicate with and answered all my questions very quickly. The city manager was also very friendly and helped us with things we needed help with.
The additional taxi pick up service at the airport went smoothly and it was nice not having to worry about it.

General comment: There aren't 80 stairs to get to the appartment (as another review mentions) but 53... and they're quite easy to climb and in the shade.

The only disappointment was that we couldn't find any 'essentials' in the kitchen for breakfast (which is something you usually get from most Airbnb rentals). It would have been great to at least have some sugar, coffee, tea and a few breakfast products.

In short, if we ever go back to Rome, we will definitely rent this appartment again! :)
