The flat was lovely and amazingly central. Perfect as I visited with my septgenerian mother and to get to all of the sites was just a very short walk away.
On the down side it is incredibly noisy. Paolo kindly provided ear plugs, but I'm afraid that they didn't block out the revelers who were seemingly right outside the window....until 5am.
Saying that the flat is priced accordingly, and it is so central that you have to expect there to be some noise as people leave the bars and go home.
To anyone else traveling in a taxi from the airport please note that there is a street that is incredibly similar in name. Make sure that they taxi fully understands the correct address. We ended up having to get a second taxi (15 euros), to take us to the correct address.
