After 4 years we returned to Prospector Square, but tried our luck with All Seasons Mgt for their buy one/get one free night prepaid offer, making cost of slightly larger studio with full kitchen less than $100 per night.
Check in was at Carriage House and more helpful than previous experience at Prospector. Room was ready, so allowed very early check in. No problems to contact desk during stay. Used key drop for early checkout. Trash was collected from unit and bed tidied.
Unit 408 on first floor had OK bathroom (toilet behind door), same sensitive hot water control in shower, no towel racks by vanity/sink in separate area. Kitchen worked fine, but no potholder, no baking dish or tray. Refrigerator cycled on/off all night. Carpet was worn but tile relatively new. Two comfortable beds, flat screen TV, this time bar chairs and tall table. Again no comfortable chairs to sit in, read, put on shoes, etc. Noisy heat cycled on/off all night. Drapes didn't fit window, but we managed. No sheers so either totally open or totally dark. 40-watt bulbs, so reading almost impossible.
Plumbing is so noisy it sounded like running water inside our bedroom when neighbors using their water.
So, OK for cheap place to sleep while skiing, but don't plan to spend any extra time in the room and don't expect a 4 or 5-star experience. Slightly larger/full kitchen not much more than the basic studio we rented before.
