When I travel, there are certain essentials, like good WiFi, a washing machine and floor dryer, ample refrigerator space, bedside lamps, surface space for my things, and an area to set up my computer, for my work.
This apartment had enough of my prerequisites for me to book it. I soon discovered that it was filled with the little things (that when missing, I have to adjust to), like continuous hot water, a large kitchen sink with a faucet that makes sense, a good shower, plenty of electrical outlets, and good lighting.
The bonus is the host, Alessandra, who is very accommodating and helpful. From her, too, I learned much about the culture of Naples. If you're planning a stay in Naples, look for this apartment.
