Hi nok,
Thanks for your message very much and thanks for your coming.
First we would like to express our sincere apologize about the unsatisfaction of the arrangement. In fact, fist night you reserved a double bed n we hv twin bed room for you, but another day as we mentioned we only have single bed room at our guesthouse. Having discussed with my staff and my mum we all think that we should pay extra for you to let you stay at really dpuble bed instead of single bed, so finally we paid $480hkd to cityplus for letting you have a double bed. We do apologize that we never think that the room you are really not satisfy with the arrangement and thanks for giving us the feedback that we cannot arrange by our own judgement which may not professional enough. Please kindly believe us that we have really no purpose to give you a worse room, really not. We are not concern about the money, but we are afraid that the initial room we arrange for you is not better than this room. And we think you are couple and prefer staying in one bed.
We do very apologize to make you unhappy with this arrangement. we promise that we will not make similar mistake next time and we do wish you will come hong kong regularly again.
Thanks for your coming again.
