  • I stayed here once a few years ago. The meals were delicious then, and I was very satisfied. This time as well, both breakfast and dinner were buffet-style with a great variety of dishes, including plenty of seafood, and it truly felt fulfilling. Everything was excellent. The shower head in the Room bath was a modern model and very comfortable. The gentleman in the parking lot was very friendly, took our family photo for us, and we were happy with how well it turned out. The view from the Room is also wonderful.

  • They were very accommodating with an early check-in and arranging our luggage for the return trip. The Hotel has a calm, long-established tropical atmosphere, and the ocean view with palm trees felt like Hawaii—surprisingly exotic and very relaxing. We couldn’t go into the sea due to high waves, but we still enjoyed the pool.In the open-air bath, there were spider webs on the ceiling.I wish there had been more food options in the lounge—especially a curry dish.
