Excellent! The apartment itself is lovely, and the terraces were glorious to spend an evening with a glass of wine or a meal. Perfectly clean. Kitchen well-stocked for basic cooking. Being on the top floor, the apartment was very bright and hot in the main room (in July), but the bedroom and main room have good air-conditioning which was great! 10 minute walk to Mondello beach, 20 minute to the Piazza and main restaurant area, and there is a small grocery store 5 minutes walk away.
Walter was an excellent host, and even drove us to central Palermo at the end of our stay (for a small fee). Would 100% recommend!
