The apartment is located on one of Naples central avenues, however it is very quiet as it faces a side alley. The proximity to the city centre and its amenities and the railway station make it a good solution to enjoy a visit to Naples. Also, the host was very reactive when we had problems with warm water. Finally, the hippy vibe and funny / funky details make add to the atmosphere.
However, this is also the downside, as the flat is not always comfortable or practical (choice of the furniture, mezzanine, etc). The heating is provided with two air conditioners, and when we arrived they were switched, which is a gesture that guests might appreciate. Therefore, the flat was quite cold. Moreover, the stairs to reach the mezzanine are steep, narrow and squeak at every step, which is not pleasant, especially at night.
Overall, the flat is ideal for a short vacation, but I think I would rather choose another solution which is more to my taste the next time I am visiting Naples.
