We had a very nice stay.
The location of the appartment is really nice, between Quarteri Spagnoli and the historical center, and very close to metro Dante which is 10 minute away from the Railway station.
The free breakfast in a café nearby was also really good, in a nice authentic neapolitan café-restaurant, with a very kind server. In addition to that, we had a nice welcome in the appartment with fresh water (both sparkiling and still) and some wine in the fridge. Also, the basics for cooking are already in the appartment (salt, oil etc).
The bath tub is nice and bigger than usual, it is great for having a rest after a long walking day. The air conditioning works fine, although the tank receiving the condensation must be emptied manually (we only used it for 1/2 hour in a row, but it could be used much longer).
Grazie Giovanni & Giulia !
