I think you need your own car. The place is not far from town but you need to pass a busy road of which I would not recommend to use as a pedestrian.
The place is situated in a very nice garden and you feel you are in a tropical oasis. We enjoyed sitting outside and having a drink. The car could be parked on private terrain only a few meters from the house.
The was clean and everything that you need was there. It is called the artist house and that name is right looking at all the prices of art that were standing and hanging around.
There was a basic breakfast available (tea, coffee, milk etc).
We used it at a short stay over to be able to start visiting the temple as early as possible. This worked out very well, No hassle with parking the car. Which I can not say about Agrigento it self but that is a different thing :)
