I am surprised that this hotel appears alongside The Library on Design Hotels' website. The Muang Kulaypan is quite literally an expanse of grey concrete, more reminisent of a 1970s English town center/prison block, than anything resembling chic. The hotel decor is looking tired and a lick of paint here and there is NOT going to renovate this place into a design classic, anytime fast.
After booking a Deluxe Inao room and receiving confirmation of this from the hotel, we arrived at the hotel only to be informed that these were fully booked and were instead offered an "upgrade"... to an inferior room. [My partner later discovered that the Deluxe Inao rooms were not fully booked, but undergoing renovation]
Fortunately we were able to utilise the hotel's emailed confirmation as leverage and eventually were able to negotiate with the Hotel's manager who kindly offered us a significant upgrade. Unfortunately the upgrade, whilst spacious, was not at all homely and the cockroaches in the bathroom, not welcome!
In the evening, the hotel's grey restaurant failed to attract custom and was therefore generally vacant and devoid of life. As a result of this, we escaped to the Amari Palm (next door) on most evenings!
On a plus note the Salas at the beachfront are a great place to eat breakfast or relax with a drink while the staff were also extremely attentive and friendly.
In summary, I would not recommend this hotel as it totally fails to deliver what it promises. Your time on Samui would be far better spent elsewhere.
