Such a lovely stay!
We were quite freaked about security in Naples because of all the things I've heard but the area that this BnB is located in is super safe and wow, what a view just outside the place!
I would recommend it location wise if you're looking to go to Pompeii or Capri. The access to these places is smooth from here.
The place was clean and had plenty of restaurants around, within a walking distance of 10-15 mins.
One advice: if you have a drag on suitcase, it's better to take a taxi from Mergellina station to the place, cause it is uphill all the way and the pavement isn't suitable for dragging wheels.
Also, the boiler for the shower has a certain capacity, so in case you take a long shower, the person going in for the second shower should check for hot water before getting into it. I ended up taking a cold shower..
Apart from that, no issues at all! I didn't meet Fabrizia herself but her father was really nice and served us breakfast every morning. Thanks for the lovely stay in Naples! I loved it!
