Guam reef provides a beautiful infinite pool where you can enjoy the stunning sunset. It also has a great location- near DFS and other shopping center, walking distance to all the recommended restaurant.
The only thing I would like to complain about is the housekeeping. At the first day, we found the water cooler leaking everywhere when we just stopped by to drop off some groceries and had to wait half an hour for a staff to repair the machine. They did change the machine, mop the carpet, but not doing anything about the curtain. Then, no replacement on bathmat and towel on second day and third day, respectively. Air conditioner dripped a little every now and then.
In general we will try other hotels next time visiting Guam.
