I spent 5 days at Casablanca and could not fault it. A charming apartment that retains all the original features. Can accommodate 4 people comfortably. Views onto the bustling street below and views to the Adriatic from the roof terrace. Cute kitchen kitted out with gas burners and all the utensils you'll need. Spotlessly clean, great shower with plenty of hot water.
Location is perfect as its only a 5 minute stroll along one of Ostuni's most attractive streets to the main Piazza, centre of the old town, with all the cafes, restaurants, bars etc.. If you're driving, no problem parking at there's a decent sized car park across the road.
Communication with Stefano (aka Luisa) was excellent throughout.
All in all, wonderful apartment, terrific location, and good value for money.
I would certainly recommend Casablanca, and will definitely be staying here when I return to Ostuni next time.
