I chose Italia's apartment because of the great reviews, and it certainly deserves these. The apartment was spotlessly clean, beautifully decorated, and had everything we needed for our stay. The view of Vesuvius was such an added bonus, especially after we spent one morning climbing it!
I had originally thought that the apartment was a little out of town and we would need to use the metro, but actually we managed to walk (with 2 kids) to the Underground Napoli experience (stopping off for pizza on the way) and also to the central train station on the last day with our cases (about a 20 minute walk). So in fact the location was great - it felt safe, even in the evening, there were plenty of restaurants and take aways, and several food stores for all the essentials, including one just a few doors down from the apartment.
Italia's communication was second to none. She always responded and was so helpful and kind. One evening we had a minor problem (which turned out to be our mistake) and she was on hand to solve the issue for us. She even provided a telephone number for overnight emergencies, which was so reassuring, even though we didn't need to use it. Italia's colleague met us at the apartment and was so helpful showing us everything (phone translation tools came in useful here!)
Italia also organised a driver for us to visit Vesuvius and Pompeii one day. If you have kids (especially ones that moan about too much walking!) then this is the best way to travel to these sites. Our driver dropped us right at the entrance to Vesuvius National Park, was there waiting for us when we finished, took us to Pompeii and organised a great guide for us when we arrived. He even asked the guide to bring us back to the right place at the end of the tour. The driver also gave us lots of information about Vesuvius as we drove there. He was fantastic. After walking up and down a volcano, followed by a 2 hour walking tour of Pompeii, in 25 degree heat, it was wonderful to get straight into an air conditioned taxi and taken straight back to the apartment.
I must also mention the amenities that Italia provides - all toiletries, towels, slippers, coffee machine with coffee sachets, everything you could need in the kitchen - everything has been really thoughtfully taken care of.
All in all I can thoroughly recommend Italia's apartment for your stay in Napoli. Thank you Italia!
