For those of you who like the finer things in life, PS are doing a great deal at the moment on longer stays or at least a month.
I've just booked a month in a Premier room for 58,000bht. This includes service charge, tax, one breakfast a day and a 2500bht laundry allowance. That works out to around 1900 baht a day. Top deal.
They are also offering 50,000 baht plus 7% tax (nothing else included) for the more standard Executive room.
