The place was simply AMAZING. You cannot get a better location. We were three blocks from the Colosseum, across the street from a huge museum that had the unknown soldier. Tons of restaurants, bars, etc. within walking distance. There is a small store around the corner for water, wine, and snacks. Also a few blocks up the road is a pharmacy. Stay away from tourist areas to find good food. There are also quite a few street peddlers trying to sell items so beware. Overall you cannot stay in a better place for the price. The facility has two doors to enter that require a key to enter and exit. You have complete privacy.
I would recommend using the Roman Guy website for tours of the Colossuem and Vatican. The Vatican is a MUST SEE. It is a lot of walking so be prepared. You can walk to every place in Rome to the exception of the Vatican. Within walking distance of her place is Colosseum, Pantheon, Spanish Steps, Trevi Fountain, Roman Ghetto, and more. All are within 1-3 miles of her home. Scooters are also an option but I would not recommend due to the crazy drivers in Rome. Get a bike if you have too. Also, tons of fountains to refill your water bottles.
Overall it was a great experience.
PS: take cash, a lot of places hate or won't take card. Use Uber as well. Taxis can be a pain.
