We were a party of nine, four adults and five children, staying in this beautiful apartment for four days. It was perfect. Beautiful and smart furnishing, stylish and well functioning bathrooms (3!), very helpful landlord, everything is working (hot water, fast wifi, tv, kitchen) and it is perfectly clean.
The apartment is perfectly located, there are very a very good jazz bar, gelato bar and pizzeria on the same street and nice restaurants and wine bars in the neighborhood. Close to Forum Romanum and Colloseum, Trastevere and cheap to take a taxi everywhere else.

I will definitely stay here the next time I am in Rome.
