The staff were great! The only issues with management is that they gave me the wrong keys the first time around,and when I received the right key, the door wouldn't unlock fully. My husband doing a way in through one off the window. Cleanliness of the home was good,though the cooking utensils were not as clean as i had wished. There was a pan with grease in it and a pot stuck in top of it. And lastly,I was surprised to find a wok there, though there was mold in it. Not very good.I went in a group of 18 and had 2 rentals, #15 is actually more modern and updated with bedding and furniture. The bunk beds on our side barely had space for someone to lie down in bed but not sit, where as the other bunks next door had a good amount of space in between the top and bottom bunks. The space was nice, though you have to make sure you do a walk through and let them know all the issues you find, since we found a lot of issues with the house. The property manager came a couple hours after we told Mammoth Sierra Reservations about the issues to check them out and fix what he could. We had a list of issues, one being the heater upstairs did not work. We had to use the fire place, though we still had to keep the door next to it open a bit for the smoke to travel out (one of the latch was missing and smoke came out the front, we had to place a heavy log to close the top door tight). Overall a good experience, but wished it was more updated and modern. We would definitely come back to this property, though not sure #17 is the right one for us.
