The flat is gorgeously bright, spacious and clean. It was a pleasant 5-night stays.
However, the first two night staying was a bit of nightmare as the temperature in Napoli was high. I couldn't fall asleep without an aircon (they have a ceiling and pedestal fan tho...). It was also my bad that I didn't check if they have aircon which surprised me on the first stage as people from Asia we think aircon is a default, but not in Europe obviously.
Luckily, the temperature was dropped after raining in Napoli that the remaining stays were fantastic!
Nice balcony, nice kitchen, nice living room, and nice neighbours. Would definitely recommend (but maybe a less hotter day).
