Great view of the bay of Naples. The house is 3 min away from a major street on top of the hill and very close to the Funicular. While the house is the one 5th floor, there is elevator that takes you up. Please note that to go up and down the elevator (lift) you will need 10 cent (euro) coins. In our case, the host graciously met us when we arrived and gave is 4x10 cent coins to get us started.
The area where the house is is about 10 min away from Via Toledo station where you get get trains to Sorrento and Pompeii etc. Lots of good restaurants in this area too.
As I said above, the house is close to the funicular that can take you down to the main shopping / fort /castle area or up to Castle Elmo.
This is a old, historical neighborhood where lots of people still live so it is not the cleanest but we found it safe to walk around.
