We had a wonderful stay at this apartment. The apartment was very clean, very very functional, the beds were good. Unlike a lot of other apartments this one had 2 proper bathrooms. The owner was very very helpful and courteous. She even had made arrangements for a baby cot in one room since I had mentioned to her about we travelling with children one of whom was a toddler. The place is at a walkable distance to the Vatican, though there's a bus stop right outside as well. The bus ride to Roman forum, colloseum etc should also take around 30 - 40 mins provided the buses are running on time.
All in all I would happily recommend this place to anyone for a nice and comfortable stay in Rome
