Clear, quick and friendly communication! In addition to the apartment being clean, modern and stylish, Marika and her family have added thoughtful details like breakfast croissants (with spreads) and cooled wine (for sale) in the fridge. They made extra efforts to make our stay a good experience, like making up for (unforseen) workers in the building by offering complimentary breakfast and allowing us to store our suitcases securely in the apartment until our departure. The location is perfect, very typically Neapolitan, within walking distance to ALL major cultural sights, as well as the metro, and with little shops in the neighborhood where you can buy fresh bread and groceries if you want to make a meal at home (the apartment have all necessary kitchen equipment). The apartment is perfect for couples.
If we ever come to Naples again (which I very much hope), we will know who to contact first.
