If the picture here is supposed to be YWCA, Park Street, Kolkata then this is a terrible deception. YWCA is nothing like that! It is like a prison yard and once you are there you are actually committed to solitary confinement as no visitors are allowed you.
The rooms are small and bare and the beds are like mere cots. There are public toilets and very few en suite rooms which you are very unlikely to get. Many noisy college students occupy some of the dorm-type rooms will keep you awake after 12 midnight!
If you are looking for comfort, try somewhere else.
