In major cities and touristic areas you can find a good variety of accommodations, from world-class brand hotels to family-managed bed & breakfasts and room rentals, but hostels are really few.Camping is a good way to save money and camping sites are usually well managed, but especially during summer, managers tend not to accept last-minute groups of young people given the high chance of problems that such groups of Italian guys tend to cause, so you'd better book in advance. Farmstays are an increasingly popular way to experience Italy, particularly in rural areas of Tuscany, Piedmont, Umbria, Abruzzo, Sardinia and Apulia. They provide a great combination of good and healthy food, wonderful sights and not-so-expensive prices. If you prefer self-catering accommodations, it's quite simple to find them on the wonderful Amalfi Coast or the less commercial and more genuine Calabria coast.
Hotel star ratings can only be taken as a broad indication of what you will get for your money. There are many marvellous 2-star hotels that you will want to return to every year and many 5-star hotels that you will never want to set foot in again. The star rating, as in all countries, is based on a bureaucratic assessment of the facilities provided and does not necessarily relate to comfort. Often the only difference between a 3-star and 4-star hotel is that the latter offers all meals while the former only offers breakfast.
