Location wise, this hotel is probably one of the best place to stay in Koror, Palau.
There's nothing fancy about the hotel, no real amenities of any kind, no free wifi, no TV, etc.
But the rooms are kept clean, shower water pressure and temperature is good, and staffs are very hospitable.
Given the fact that your main activities in Palau are mostly outdoor activities out in the water, and I'd say you really don't need anything more than what's provided from the DW Motel.
