Place to stay in Sorrento for a family of 5

check out ilnido.com. Hotel il Nido is above the city but offers great shuttle service. I've stayed here alone and brought several guests over the past decade. This place is very reasonable while maintaining a friendly, family atmosphere. I think you'll be pleased. I know it isn't an apartment but I maybe it might work for you.

we have booked tasso suites apartment, for 5 adults in May. we have stayed there before as a couple, this time there are more of us. so we will be interested to try their apartment. we found it a great location, which is important to us.
