Amazing very cute apt centrally located with all modern updates. Tiana was kind to meet us on arrival, provide great directions as we arrived by car (Watch for ZTL times), and met us last minute for departure. The apt is ground level and used to be a shop. Now it feels like you're a local with lots of green plants as you approach the door. There is a huge downstairs that we never used. The shower is tight but very modern. The street is very quiet and amenities are great. The bed was the most comfortable one we had on our 2 week trip. Tania has a folder of recommendations for food (with 10% discounts) and sites. There's a cute (1# on trip advisor) sandwich shop called My-Ale, directly across and a good restaurant next door. Tania was also kind to provide some water and juice for our arrival. Made my return to Rome after 15 years perfect and would definitely stay here again. Hope to return soon.
Other tips: We got the 48h bus/metro pass and it was easy to get anyway via buses around town including directly to the main regional train station. Water is ok to drink from the tap and running small fountains (unless they say otherwise). For more local eats, check out Trastevere neighborhood just south. If you spend day at the packed Vatican, consider going to Pizzarium some of the best pizza i've every had;) If you visit Sistine Chapel, go out the back right door directly into San Peter's.
