What a wonderful place! First of all- the location is just perfect- 50m from Spanish Quarter and Pignasecca street market full of delicious food and stuff. Supermarket 20m. About street noise- if You live in the centre then it's absolutely normal but as the flat is quite high (there is elevator), noise doesn't reach so high. I was using earplugs and it was completely OK even on Saturday night. And this beautiful furniture, it is really ancient and precious- worth of close looking of these masterpieces. Hostess is very nice and helpful, gave us lot of suggestions to our trip to Napoli.
