We have just stayed (August 2020) at Marika's flat in the Spanish Quarter and had a great time. The apartment was spacious and clean, is newly-renovated, and is a great base to explore Naples and the surrounding area from.
Marika met us at check-in and was very friendly and helpful, and also responded quickly to questions we had about local sights.
All in all, a great place to stay and great value too.
