The apartment is perfectly situated on the edge of the old city center and close to everything in the center and harbour. Everything is in walking distance.
For Naples, the appartment entrance is in a quiet corner, a small plaza with a nice bar and some green. The windows are along a narrow street and you'll hear everything if you open them, and you want to because it's kind of 'basement feeling' for us in the end of the week. But you'll be outside on the streets anyway because that's where's the life! :)
Best part is the amazing friendlyness of Antonio. He takes the time to give you tips of where to go, to eat and drink which you might not find without him. And if you need more info he'll reply instantly! Best Airbnb owner experience I had so far.
