We stayed there for 7 nights and it was a great location for us to explore the city (two adults, no children).
When we arrived we had fresh fruit and a bottle of wine waiting for us, not to mention great collection of coffee (Nespresso) capsules with a proper coffee machine!
Half way through our stay Alessandro arranged the cleaning of the flat, which was a nice surprise for us!
The location allowed us to explore many sides of Naples: just a couple of streets away there is a street market, with fruit and vegetable stalls as well as huge collection of plastic shoes. To the other direction there is main walk through the old town streets. You can walk to the sea in half an hour or just take a metro, which is 10 minutes walk from the flat.
