Marzia and her husband are absolutely wonderful hosts! I was greated with a warm welcome and a clean and fully supplied bedroom/bathroom/shower that is true to the pictures shown. The apartment is on a higher floor and one afternoon I thought it would be fun to take the stairs on my way back to the room, but save yourself the heart attack and use the lift that's provided! ;) As well, there are lovely neighbors in the building that I met during my stay!
The location is perfect for those who enjoy quiet, and considering how busy Rome is in general, I definitely enjoyed the peacefulness. I chose the location though because of St. Peter's Square being so close, about 5 minutes by walk. In fact, the location is perfect for a day around this area to beat the lines especially for St. Peter's Basilica and the Vatican Museums. I visited both within the first hour of their opening hours and missed the lines completely.
I am a female in my early 20s and was traveling alone for 4 days (3 nights). I felt safe and comfortable walking to St. Peter's after dark or waiting for the bus during the dark at the couple of stops located near the apartment. There are also metro stops that I used that can be reached by an easy stroll through St. Peter's and past Vatican City. Both metro and buses are very easy to navigate and can be used to put you within easy walking distance of popular locations such as the Colosseum and Roman Forum, Pantheon and the Spanish Steps.
There is a popular pizzeria on the same block as the apartment called Papa Rex that was pretty tasty but very busy! As well, there is a bar a couple doors down for a quick breakfast and some lunch items. I spent a lot of time though on the street that runs just on the outside of Vatican City and found countless pizzerias, bars, and shops.
Although I didn't see Marzia and her husband during my stay, I felt like I could've popped in whenever I needed something! I was provided with a map of the city and books if i needed them about the language or the city. I would absolutely recommend this room for anyone's stay in Rome! I hope when I'm able to return Marzia will have room available for me to stay again :)
