The Good: 1) only a 10 min walk from Village shops/restaurants & Canyon gondola, albeit a bit steep in one direction; 2) right near a bus stop (though did not try); 3) decor is a bit more modern and airy than typical wilderness woodsy look of other condos; 4) in-condo washer & dryer.
The BAD: 1) BEDROOM DOOR HAS WARPING OR PAINT ON TOP EDGE WHICH DOESN’T ALLOW IT TO CLOSE WITHOUT HUGE SLAMMING SOUND, WHICH MAY WAKE UP OCCUPANTS; 2) BATHROOM: CEILING HEATER DOES NOT WORK, shoddy overall, tacky stucco & cheap tub/ sink/ furnishings straight out of a cheap apartment, w/ poor paint & sealant job, tub with some slow drainage, and one towel bar literally flew off wall into tub (which was dangerous) as was not tightly mounted onto wall; 3) no central heating (not sure if such is common in Mammoth); 4) space heaters, while apparently strong, have NO READABLE INDICATIONS ON DIAL SO CAN'T TELL WHICH WAY TO TURN, NOR EVEN WHETHER IT IS OFF/ON OR ON SOME KIND OF THERMOSTAT OR AT WHAT TEMPERATURE; 5) front door SQUEAKS LOUDLY UPON OPENING OR CLOSING - BADLY ENOUGH AS TO HARM ONE'S EARS; 6) motion sensor light outside door was apparently out of batteries, making it DANGEROUS trying to figure out where downward staircase begins in the DARK; 7) walls somewhat thin - could hear quite a bit of walking / furniture moving from upper floor; 8) privacy not great at windows, as are at ground level; 9) parking spots do not have unit numbers, so parking is a free for all; 10) no onsite office.
If this were rented out at a cheap rate, the location may well make it worth it. However, the effective nightly rate (incl 'owner' and service fees) was EXORBITANT -- for that, you should get actual luxury. Caveat emptor!
