Salvatore was fun, helpful and very accommodating even though we were arriving late in the evening. The apartment is so stylish, decorated amazingly and fun with all the levels and the super cool roof deck. You can make coffee and tea and there is a small fridge to keep all your delicious market purchases fresh. Salvatore recommended a few restaurants and we really enjoyed the two we visited. There are a lot of stairs (4 flights), but we only had backpacks so we didn't mind.
Great neighbourhood, very central and lots to see close by. It is a 20 minute walk from the bus/train station. We had two taxi drivers tell us they didn't know where it was (Piazza San Domenico), so perhaps print out a map or know your cross streets so they can't give you the run around.
