This hotel is no doubt an ex-mall. Bed was nice, and I found the front counter staff to be quite nice. Bathroom shower was broken, very limited bathroom amenities (only 1 very small bottle of shampoo, just enough for 1), and a small thin soap. No toothbrush, shaver, comb etc.
Buffet breakfast there was the worst I have ever seen. None of the food was kept warm. They do fried eggs (only fried), and if you don't get them soon after being cooked, they will be cold too. Some fruit, and 2 juices, but if you are doing your breakfast a little late, fruit and juice may be gone or limited, they don't re-stock. No cereal. White bread only, can be toasted, butter supplied and one cheap jam/jelly.
Directions to the hotel on the hotel site are not accurate - I found 2 different ways for the site to show you where the hotel is, and they are both wrong. It is actually on the corner of Petchaburi Road and Soi Petchaburi 13.
It is a pretty quirky place, and because of that, I wouldn't say don't stay here, but, if you do stay, do yourself a favour, don't book in for more than 1 night!
