If you come to Naples, stay with Renata!! She is kind and thoughtful, and her dog is a sweetheart. Check-in was super easy, and the place is in the heart of the unique and lively Spanish quarter. It's close to restaurants and the metro.
The room is perfect as well - it is its own little entity complete with a small kitchen, a wardrobe, and bathroom. Plus, you have an AMAZING view of Vesuvius and the sea, perfect for sunsets. This place truly is a gem.
