Marika's place is very clean and in a perfect location round the corner from the train station. My friend and I (both female) always felt safe walking around the area irrespective of the time of day/night. We stayed in the summer and the aircon was very effective! The apartment is located on a lovely street with restaurants below which can be seen from the standing balcony which is perfect for observing the street life of Chiaia. We were undecided on whether to stay in the heart of Naples or Chiaia and were very pleased with our decision to stay in Chiaia as it was safe, with plenty of food/ drinks options and close to the train and only a 20minute walk to the port to catch a ferry for say trips to Capri/ Sorrento.
