I have stayed here on two different occasions out of the four times I visited Kampaeng Phet and this is trully one of the best hotels. It's small with a pension like feel and very easy to find from the big road.
It's a place where you can relax and the room has a nice view of the swimming pool.
The staff is very attentive.
Rooms look good and the bed is comfortable, clean and with a nice duvet. Pillows are too hard.
The bathroom needs some improvement.
There is a light odor coming out from the drains and you notice it if you let the bathroom door closed. Otherwise it's not bothersome. The shower hose is short and cannot be adjusted high enough to stand below it. The corners need a little bit of cleaning, touch up.
What I did not like is that they provide you with flip flop style slippers which were not new. Better give new cheap paper like slippers, than used good ones.
They provide nice Thai massage, although you should be careful and tell them if they go too hard on you. Actually the "spa" is a massage and manicure.
Breakfast is OK but after a few days it becomes repetitive.
I would say, do not risk staying somewhere else.
P.S. they can have you food delivered to your room if you do not want to go out for lunch or dinner.
