The room was really big, with a double bed, small sofa, private bathroom and private balcony. The air conditioning works perfectly and it's quite silent. The mattress was a bit too hard, but we could sleep comfortably.
The breakfast is very complete with tea, coffee, pastries, cookies, yogurt and fruit.
We loved also the location, it's close to everything at walking distance: restaurants, the old town, the port, and also the metro to get to the train station. The main street next to the place is busy all the time, so you can get late at night safely.
Danilo, the host, is very nice and he recommended what to see around the city and how to get around to Pompei, Capri, etc.
