Blew away our expectations! Absolutely gorgeous inside and out with a spectacular view and all possible amenities. I raced ironman and we celebrated our girls birthdays while there (ages 13 and 15). They each brought a friend and everyone loved it. No one wanted to leave. It was quiet and out of the way yet sooo easy to reach Lk Placid village and my family had no problem navigating to and from the race venue and course. Would stay again next time in a heartbeat. Perfect week and the owner was wonderful to deal with and very helpful.
PS: if you are uncertain about IM Lk Placid - it's awesome; the scenery, energy, spectators, sightseeing, recreation...And stay at Serenity!
