Nice location a few minutes from the Vatican and the Metro. Apartment is spacious and well stocked. We stayed for 4 nights and had a lovely time.
Only possible criticism is we got caught with no hot water a few times. The hot water tank isn't that big, therefore we had to keep waiting for it to fill up to enjoy long hot showers.
We reported the issue and were told it's the maximum size the local legislation allows apparently.
Apart from this the apartment was lovely.
