We stayed here in the height of summer, so the shaded pitches were a godsend to keep the tent nice and cool. The pitches were a liitle on the small side, and very nearly one and a half hours, and one divorce later, me and the wife had made a tent that was too big for the pitch fit.
The toilet/shower block facilities were big enough and very clean too.
The pool was ok (yes, you do have to wear a cap, but if you know that in advance, take one with you) and there was actually decent entertainment laid on in the evening too.
There is decent information about cycle trips, things to do and the local area on the notice boards, and the staff were knowledgable.
There is a shop onsite, with fresh produce available, but also a supermarket close by if you want to economise.
If you're touring, then it makes a good base for the area, as Pisa itself is very pretty, with the obvious attractions, but you would struggle to spend more than a day, maybe two, without needing to venture further afield.
All in all, very good value, decent campsite, with an excellent location for visiting the leaning Tower etc.
