Beautiful, large, sunny apartment in a relaxed, upscale neighborhood. Full of antiques and with a well-equipped kitchen. Francesco's parents met me for check-in, they were very friendly and kind, also flexible when my flight was delayed. They left a helpful binder full of neighborhood restaurant recommendations.
The piazza gets a bit noisy with cars, schoolkids, and bars, but it's quiet with the windows closed or even with the windows open later at night. Vomero is not walkable to the city center, it's an hour downhill plus a serious hike to get back, but the metro is close by. I would be very happy to stay here again, this neighborhood has plenty of shopping and restaurants, and I'd rather be a short metro ride away than right in the center of Naples. I would definitely pick this apartment if I came back.
