The Simplitel is a good value. The rooms are quite large and simple, with nice modern furniture. The king size bed is large and quite nice. The bathroom is small, and my only complaint about the hotel is that the bottom of the shower curtain had mildew on it. The aircon is great and we liked the balcony too. The TV is a nice flat screen, but there are very few English channels. The room has a hair dryer and safe. One day we did not put the "make up room" sign on our door and housekeeping never cleaned our room. We didn't realize we had to put the sign out.
Breakfast is included and it was just ok. It was small, but we enjoyed the fried eggs, bacon (or ham some days), fresh fruit, and yogurt.
The location of the hotel is great, right in the middle of busy Karon - near lots of restaurants and shops. It takes about 5-10 minutes to walk to the beach. There are lots of ATMs and little mini marts nearby for anything you may need, including an ATM and small 24-7 mini mart right next door.
If you don't have to stay right on the beach and you don't mind not having a pool, the Simplitel is a good value, in a good location.
