We visited Rome as a couple and this apartment was perfect for our stay. It is just off Campo di Fiori, so near the hustle and bustle but not too noisy. 10 mins walk across the river to the bars and restaurants of Trastevere - perfect for evening food and drinks so we didn't have to worry about getting back.
The apartment is a good size for a couple and very stylish. The terrace is perfect in the hot weather. Be warned there are a lot of stairs to get to it - good exercise after all the pizza!
We had good communication with the host's friend Agnese who arranged the keys etc.
I would recommend this apartment for a couple wanting a base to explore beautiful Rome!
