Amazing location, lots to do right outside the hotel. The room itself was nice and comfortable. There were a few cats in the main lobby area which we loved.

Room was clean and great location beside the beach. Room had kitchette and big fridge, microwave etc. so was great. It was dated and internet didn't work in our room but worked well in the lobby. Great value for money :) happy with it.
