It's hard to think of any issues, as there really weren't any. 1, that I know the people who run it would take into account, and act upon, was that the rooms needed to be aired for longer before our stay. This was a very small oversight on their part as everything else was faultless.
I liked the peaceful location; the size of the accommodation; the home-made breakfasts; and the friendly managers: Valerio and Luna.
Though the guesthouse is some distance from Castellaneta, it was not a problem to be transported, at a small charge.
On top of this: the TV channels available were good, the WiFi strong, no advance request was a problem, and little requests were, likewise, fine.
This is a good venue for people who like peace and quiet / nature / space. However, being so well-suited to events, I would also recommend it to those seeking a memorable location for a wedding, anniversary or Birthday party.
