We stayed at the Juniper Springs Resort in Mammoth Lakes for 2-nights in early Sept ($125 + $20 resort fee). The resort is a complex consisting of a large 3-storey main building housing the lobby and the largest pool area (pool, 3 jacuzzis, bocce ball court), a second similar building (with its own pool) up the hill, and a cluster of townhouses behind. The overall design was resort chic, with attractive stone work, wood beams and faux cedar siding. The resort was clustered near the base of the Juniper chairlift (distinct from the main chairlifts near the village) and did not offer much in the way of services nearby; they had a free shuttle, though, and it was a short drive to the restaurants and bars of the village.
Our 2nd floor suite, in the upper building, was huge in space and elegant in style. Upon entry, the bathroom was to the right and the fully equipped kitchen (full size refrigerator, stove/oven, microwave, dishwasher) to the left, with a large sitting area in front leading onto a spacious deck (with 2 plastic chairs) overlooking the valley. The sitting area had a round table with 4 chairs, a hide-a-bed couch and arm chair facing a gas fireplace, and a low cabinet under a large, wall mounted flat screen TV. There was a selection of DVD's, magazines and books, and plenty of towels for the pool. Full maid service was provided, including cleaning the dirty dishes.
The bedroom was large, with a king bed and end tables, chest of drawers, small wall mounted TV and a large closet. It had a floor fan and a strange air conditioning device into which you poured ice and water so, presumably, summer heat in the non-AC building is sometimes an issue. While we were there, the room did heat during the day, but the fan was adequate to cool the room by bed time. Sleep quality was good, with a dark and quiet room and a comfortable bed.
The bathroom was moderate in size with a tub and shower that showed their age (old fixtures, tiles that hadn't been cleaned for a while).
The pool area in our building was not properly maintained, the jacuzzi was totally unusable due to floating dead insects, and the loungers did not have pads. The pool at the main building was much better, but 2 of the 3 jacuzzis were not working.
The Juniper Springs Resort was a reasonable base for visiting Yosemite National Park from the east. The quality delivered was much higher than in Lee Vining, and the price was much more reasonable than at hotels right in the village. At $145 a night, though, they need to upgrade to AC and pay more attention to pool maintenance.
