First of all: great apartment and perfect for our needs! So every 'criticism' is only a few points taken from 100 percent.
First, the location is amazing! You live in between the locals, so you feel a little less like a tourist and pay local prices. On the market in front of the door you can get anything from tomatoes to shoes. They start to get ready really early so if you like to sleep with an open window, it can get loud. Little breakfast places, uncountable mini markets and great restaurants all in walking distance. (We recommend 'Il Sale'! One of the best meals any of us ever had!)
The apartment itself has character and the terrace is just perfect! Only once did the neighbour have to remind us that his bedroom is right next to it :) If I wished for anything, I would say a few more things in the kitchen: two more mugs, at least one sharp knife, maybe an espresso maker. But thats it :)
And a few words to Gaetano: fastest replies and the organization of the transport from the airport (in the middle of the night!) with our private driver was perfect.
We would gladly stay there again!
