This is a hotel that mainly caters to the Japanese as there are many such visitors to Palau. For the price, this hotel is a good value for a typically expensive or lackluster accommodations in Koror. The decor throughout the hotel and grounds is of wood and rattan, so it gives a very local vibe, instead of the center of town hotels that are built entirely of concrete.
The hotel offers Japanese style amenities such as Shiseido toiletries, gift shop, even teppanyaki if you're so inclined, although quite expensive. In our 3 day stay, we only saw 1 other person who was not Japanese, although this European man looked quite lost in the resort. This is not to say that English is not spoken here, as all of the staff do speak some English, and the Palauan staff speak it quite well.
The hotel seems to lease out a space to a restaurant called the Jungle Bar, which serves a combination Palauan, Filipino, and Japanese cuisine at a reasonable price (for Palau). We had one of our better dinners here. Draft beer is reasonably priced as well, but unfortunately the space is more like a jungle decorated dungeon. They do the best they can, I suppose.
One word of warning is that there is nothing to eat from 2pm to 6pm until the Jungle Bar opens, so when you get back from your tour typically around 4 or 5pm, you're left with a local store about 50m from the gates for some chips and soda/beer.
Another slight bit of annoyance was the high price of airport transfers. Coming into Palau at night really leaves you no other choice though, but to pay the $20 per person each way for a 10 km, 20 min ride.
