Antonella’s studio is nice if you want to spend few days in Napoli. Be aware that there is no kitchen and make sure to be able to open the front door because her keys are tricky!
Also, I read in the previous comments that the wifi has never been an option but it is an excuse to explore the city as her studio is near such cool areas and the beach is only 15 minutes away.
The place was very clean and the bed for two comfortable, I did not suffer from the noise and she has been welcoming and fast to reply about my issue with the keys.
I recommend for short stays only :-)
