Marco was a very friendly and accommodating host - very prompt with replies and attentive to making my stay as enjoyable as possible. He gave a lot of tips on where to visit and where to eat, and even escorted me to the train station when I left. The flat itself is very clean and is in an ideal location (very close to great pizza places!) The bed is a pull-out sofa but it was comfortable and the apartment was very easy to heat up. The toilet strangely did not have a seat, but the shower had plenty of hot water. As it is on ground level, you will definitely hear the noise of the narrow street, but it's not so bad at night. The flat had everything I needed and it was close to many attractions. I'd recommend this place (and its great host) to anyone visiting Napoli!
