Yes I stayed at KRS many times now. Twin Pines is their 1st B&B & KRS their newest. Twin Pine is real B&B hostel concept wth shared bathroom. KRS is more for family & couple with own attached bathroom and clean.

Yes you need to call them 1st to book and pay them by banking-in to their bank a/c. Walk-in depending on luck. If they said no more room, you can try walk-in but for sure I hate doing this bcos you will be walking from one hotel to another and check..furthermore walk-in rate is expensive bcos they know you are desperate for rooms
