Great location. Just less than 10 minutes walk from the entrance to the Vatican Museum. The Metro Cipro station is 5 minutes away (2 blocks) and takes you all over Rome. You just basically stay on that Line A (orange) route and it passes by pretty much every sight to see including Villa Borghese (Flaminio station), Piazza di Spagna (Spagna station), Termini (Basilica di Santa Maria Maggiore). Once you get over by Spagna, you can walk to pretty much everything else like Piazza Navona, Trevi Fountain.
Back to the place. Donatella's brother Massiamilio? (I called him Max) was very informative and gave me a quick tour around the neighborhood upon checking in to show me some quick bites to eat, etc. He also showed me how to work the keys. There's one key to the building, one key to the unit, and one key to the room. He even gave me a fan cuz I came during a very hot week. Great value and I would recommend the place to anyone needing an inexpensive and good location to stay in while visiting Rome.
