I spent 3 wonderfully relaxing days in Favignana over the April 25th holiday. Although I didn't meet Diego himself, he took care of me and I was met at the port by his friend and taken to the apartment.
It was perfect for me (I was travelling alone so I found it very spacious), and I loved all its original features.
The description is however misleading as it states 2 bedrooms, and 4 beds. There is actually one bedroom, with a very comfortable double bed, (and a fold-up single bed), and a small, double sofa-bed in the living/dining-room/kitchen.
If I had stayed longer, and in company, I would have loved using the barbeque up on the roof terrace.
I would definitely return here. Thanks Diego.
