I'll counter the above poster with an absolute RAVE for Civilian! We've stayed there 3 of our last 4 Bway trips. Negatives: There's no lobby at all, just a single bench stolen from one of David Rockwell's sets to sit on. There's no walking space around the queen beds that plug the end of each guest room. And the smaller rooms have zero storage space (--ask for a larger room to get a freestanding closet-rack). BUT...
Positives: those rooms are designed with high style from end to end. Beautiful bronze fittings in the bathroom, velour swags around the super-comfy bed, elegant stencils on the ceiling. Behind the entry on the ground floor is a lovely breakfast room, perfect for coffee and continental snacks (but no breakfast). One floor up is a super-comfy lounging room with a dozen or more 1/2" models of current and past Broadway set designs on display-- just spectacular if you're a design fan like me. There are multiple sketches of set designs for one show, "COMPANY", as seen in countless revivals plus Aronson's OBC design. Scattered around the public areas are many more original sketches by Boris Aronson, Tony Walton, et al. There's also a small nook on the 2nd floor with display cases featuring props and costume pieces of several smash shows (Phantom, Into the Woods, and MJ were featured last time we were there). Even the elevator wallpaper is a nod to great costume sketches in Bway history.
Anyone who's a fan of this site will be on cloud nine with a stay at Civilian (and believe me, I have no financial stake in the place, tho I wish I did.)
