If you are looking for a stylish, clean, and well-located apartment to stay in Napoli, look no further. The apartment is in the very heart of the historic town, literally a few meters from several major piazzas, dozens of restaurants and gelaterias, souvenir shops, and major tourist attractions. As an unexpected bonus, there is a taxi stand a few meters away (it's not entirely obvious, if you're a foreigner, how to get a taxi in Napoli's old town). Inside, the apartment is exactly as shown on the pictures, with a very stylish layout combining antique charms with modern amenities, extremely clean throughout, and easy to reach. The wi-fi is very good. One thing I would note is that it is perhaps not very convenient for people with physical disabilities, as there are fairly narrow spiral staircases leading to the sleeping area and the WC. Other than that, it is simply perfect.
In addition, I'd like to mention the hosts themselves, Lucia and Gerardo. We arrived late for our check-in due to our flights and it was pouring rain. Gerardo was waiting for us at the main gate and promptly led us to the apartment and showed us the facilities while giving us valuable tips for visiting the city. Even nicer, on our departure date, Lucia and Gerardo let us stay way beyond check-out time because our flight was late in the evening. Of course, this is not something to expect every time; in our case, we were lucky that no one was checking-in the same day. Still, not every host is willing to do that and it saved us many hours of wandering around with our luggage. Overall, Lucia and Gerardo could not have been more welcoming and helpful, and I would, with great pleasure, stay in the apartment again should I return to Napoli.
