Any information on this building ?

Why is everybody fleeing ?

Also maintenance seems very high

I don't know what's going on here, but I can only speculate it has something to do with the construction further west on 49th St (between Park and Madison)? Maybe some negative effect from that?

Well, the maintenance looks pretty high... Perhaps some recent event that drove it up?

It's an all-studio building, allows pieds-à-terre, allows parents buying for kids, and is in midtown, so you'd expect lots of turnover.
