Mark's place is a lovely mediterranean island style room with a comfortable outdoor area, located few minutes bike/scooter ride from Via Roma (main street).
The inside is basic yet very well curated and functional.
The outside is quite relaxing, perfect for breakfast, lunch and dinner (be aware that the guest accomodations are next to each other so if you need absolute privacy while eating or relaxing at night you should probably look for an independent house).
In the garden there are a few small grills perfect to barbecue (we followed Mari's husband advice to buy fresh fish and cook it at home, with 20€ you can get the freshest local fish, vegs, fruit and grocery enough for 4 meals (we didn't tried any restaurant, most around Via Roma looked good but pricey, those farer than Via Roma are probably a better option. Breakfast and night gelato/granita tough, is a must to have at town cafes).
As for Mari and her husband Enrico, they have been the perfect hosts, efficient, helpful and also willing to spend a few minutes chilling out and sharing as much as possible about Lampedusa and Eastern Sicily in general.
After leaving, we were totally satisfied and definitely willing to go back!
