Our stay in the apartment was incredible! The flat itself is well furnished and with modern conveniences, so our week stay was pretty comfortable. All communications are close and even there are plenty of little fresh markets around the corner. The neighborhood is not that welcoming though =D, but you can get used to it somehow. Also, I would mention that the streets are too narrow and the pedestrian ways are parked with cars and scooters, so it gets sometimes too dangerous to get home at night. Get ready for the over impulsive crazy drivers =D. The city is very small, no need to use a metro every day, but it is, though, worse to visit some of the metro station such as Università and Toledo. I would say that the surroundings of Naples are more attractive and interesting than the city.
So all in all everything was great! Raffaele is a nice person, who lives just in the next flat. He allowed us to use his umbrellas during the rainy days and even allowed to leave our luggage after check out until evening. I definitely recommend his apartment.
