The property was very well maintained and a short walk to the beach. Debbie (property manager) does a great job of keeping the facility in tip top condition for the guests. She was friendly and kind to us and other guests, addressing us by name. She was helpful with any questions we had. It was a fun and relaxing three day getaway.

MayDee Suites is truly a hidden gem. Free parking, friendly staff and cold air conditioning are just some bonuses. Close to beaches, shopping and restaurants, so it's a great value. I highly recommend this place.
