We'd definitely recommend this apartment to friends! The hosts are very sweet and eager to help with any questions - thank you!
The place is very clean and well kept. In terms of the location, it is in the center of Naples. Most things are within walking distance, but the train station is close by in case you don't prefer walking. Many museums are a short walk, as is Piazza Bellini, which is a nice place for coffee or drinks.
Generally, if you stay in the center of Naples, opposed to the outskirts, you will get more of an authentic experience, which is much recommended.
