We had a great stay at allesandro’s with our kids - the family were great and their mum baked my wife a birthday pie! Its a very old building, and gives a sense of how people live in the city, and also surprisingly quiet for being so central. Great for visiting pompeii, the circumvesuviana station is a 10 min walk (taxi from central station is €6). Handy supermarkets nearby (there’s one high end style market a 5 min walk away that’s worth a visit) and round the corner from the uni are loads of great pizza places. Highly recommended 👌
