I stayed here with about 8 other colleagues for a business trip. We did not really eat the breakfast and it was just OK. The staff were awesome, the room was clean, ice and water machines on each floor was a very nice amenity. The bar staff and drink options were great. The hotel offers a large food menu. We did not order food but the dishes I saw coming out looked good. The location was perfect in downtown which is now cleaned up and seemed very safe.

The staff were friendly and helpful. The location was within walking distance to most anything we wanted to do. We had a family member that had surgery at OSHU. The only downfall was there is no shuttle to get you two or from the hospital.
