The place is great! Just what you need for travelling to Rome, location is accurate as mentioned in the post, close to the Vatican and really easy to access to the center of the city and all famous spots.
Mariastella is really nice, she provided prior to our arrival a lot of useful information for our trip, she is an amazing host, kind and she even had a few welcoming snacks that were marvelous since we were starving!
Walls in the place are really thin though and neighbors are quite noisy even during week days. The only thing that we were a little surprised is thay she requested for an extra tax payment at our arrival that we were not aware of, not a material amount but did was something that we hadn't considered.
But would definitely come back to this place, highly recommended!
