My family (grandma, mom, aunt, teenager, +2 babies) stayed in the back unit for a long birthday weekend at Alyeska and I cannot recommend the condo more highly. We walked in and immediately felt right at home. We had an absolutely wonderful time and plan to come back many, many more times in the future.
We had a 7-month old and 2 yr old with us - the condo is baby/child friendly, with safety screens covering the stair railings and a spacious main floor to spread out. We needed to rearrange some of the furniture (coffee table, floor lamp) to be a bit more toddler-friendly and block the stairs, but otherwise the house was perfect for our little family. The downstairs room was fantastic for the littles - blocked noise and light for naps, while the rest of the family could continue to socialize upstairs.
Kitchen was well stocked with cooking utensils. Fun fireplace to sit in front of and dry out wet snow gear. The sauna and hot tub were a HUGE hit with everyone and used throughout the day/evening. We were able to easily walk 5-10 minutes up to the mountain; easy to pop back and forth for naps, snacks, and cocoa breaks!
