I really like the convenience and security of booking through Agoda.com. They also have a very handy app which you can download to your mobile. You can get a better deal from the hotel directly after your first stay but it’s a good way to get started. The reviews and pics are helpful as well.
Keep in mind that breakfast is usually extra so looking for a bundle is a good idea. An option is trying a local restaurant or food stall nearby the hotel works well. If your accommodation includes a small fridge, a visit to your closest 7-11 can yield sufficient grub for the next morning.
