Hello all, need a short stay hotel in Manhattan.  I am in the 50's on the Eastside.  Can anyone recommend something close and clean????

All short stays are dives, but they have beds and that's really all you need.  

Portland Square located on 47th between 6th ave and Broadway

La Samanna Inn 25 W 24th St
