The "hut" has been abandoned and is in serious disrepair: see this photo from December 2011. Most of the tiny cabins (just big enough for a couple of very close friends to sleep in) alongside the "hut" are also falling apart. (Three looked in excellent condition; didn't see the inside since they were locked.)
This picture is an old one indeed. I know there was an project ongoing to repair it and I'm not sure if they finished it even today. Currently it probably looks like in your picture. I don't know for sure cause I always used the west entrance lately. Most people seem to do the same.
