You actually pay quite a bit... I agree that the garden is wonderful and it is a nice walk down towards the bay, but the so called museum (2 rooms upstairs) are not worth the money. It is a collection of old books/pictures and little pieces from here and there. As i am Austrian and used to old historical things, I was not really impressed.
Anyways, the garden is great with stunning views and the walk past the old olive trees and down towards the restaurant is just a must do.
