I stayed in Rosa's apartment for 4 nights. It is situated right in the centro storico from Cefalu so a lot of points of interest are close by like the cathedral of cefalu, little shops and restaurants. You can also walk to the beach and the train station within 5 min.
As there is no parking space on the property, Rosa was so kind to meet me at the train station (where I parked my car – it is safe to leave it there) and drive me with my baggage to her appartment. Communication with her was very easy and polite.
The appartment was very clean, the kitchen has everything one needs to cook a simple meal and especially the view over the roofs of Cefalu is simply marvellous. The internet also works perfectly.
Maybe the only critic point is that the shower is small and there could be a little more water pressure.
If I ever come back to Cefalu, I would definitively stay at Rosa's place again.
