For a party of 9 (4 adults and 5 kids) we found the space both inside and outside superb.
The local medieval towns and villages provided all we needed for supplies whilst Terni train station (10 mins from villa) gave us an easy 50 minute train ride into Rome.
The internals of the property were good. The kitchen large and ample enough to cook for 9 with the loggia having seats and dining for easily over 10. We ate outside every evening.
It is worth noting that the kitchen was well appointed with large cooker, two fridge freezers (food & wine), more pots, plates and cups than a professional cooks kitchen and a really useful central island.
The pool was excellent but also a little disappointing too. The tiling round the pool needs urgent attention. With cracks and lifted tiles it was at times unsafe and gave for precarious steps being taken. The owner was aware of the need to fix and I do expect this would be resolved to the same good standards as shown elsewhere. The actual pool was amazing and never below 27 degrees and caught the sun all day. The views were also great and was a lovely spot to soak up the sun and drink a wine or two!
The wildlife was abundant; lizards, small frogs, foxes, and yes mosquitos.
There were some local dogs which visited the villa at times looking for food and even took to sleeping under the loggia at night. These never posed a real issue other than the occasional barking at night which did disturb some of the party.
There were masses of things for us and the kids to do. The star gazing with the telescope was amazing, table tennis awesome, badminton great fun, loads of board games, DVDs, books and more.
Overall we would certainly recommend for a large family this property. We also would return if we didn't enjoy choosing different villas each year. It was a great holiday in a great location.
