  • This is my favorite accommodation.

    This was my fourth stay—I’m a repeat guest. I’m always comforted by the warm hospitality of the staff.I’m giving 4 stars because dinner felt less filling than before. I’d be happy if you could serve local fish. Breakfast was excellent, just as expected. I’d love to come again.

  • Excellent value for money in Room comfort

    The Room was spacious and very comfortable for the price. The food was average, but hot dishes were served hot. The staff were efficient and cheerful, which made our stay pleasant. The private rooftop bath felt very exposed to view from the surroundings. The large open-air bath was excellent.
