I read that Russians complained they were not able to get single rooms for their 24 hr quarantine while they waited for the test results. I think Tiffany Zagorski was roommates with Boikova. Not sure if that changed later.
Another story I've seen was from Zach Donohue and he was alone in his room.
Well not having them in solo rooms is dumb - what if skater A and B are rooming together during that 24 hour period and the Stockholm test comes back positive for skater A but not skater B, skater B would still be in a jam because they were "exposed" to skater A who has a positive test result
