Flight
Milan-Malpensa Airport is the closest to the venue (42 miles) about 55 minute drive
Hotel
No room blocks unfortunately
House Or Rental
You can look up places based on the location of the Villa. Just remember, it is a lake so be aware of places that are across the lake if you do not want to have to drive or walk far (I mean if you do get one across the lake, you could always rent a boat ;) )
Train
There are cars that can be rented at the airport for an easier option to get around, but if you are looking to not drive on the other side of the road ;) there is a train from Milan Malpensa Airport to Verbania-Pallanza. I am not sure where it drops you off in the town, but you can always map it out in relation to where you are staying. It is affordable for a one way (about $12).
Rental Car
There are major rental car companies like Enterprise, Hertz, etc. that are right at the airport if you would like to rent and make it easier to explore :)
