Unless you are 5' tall, you will not be able to lay on the "couch" without extending over it.
You get what you pay for: it's 20 bucks a night, which is markedly cheaper than other budget options in the area. I stayed for 6 nights and I'd consider staying again but only for 2 maybe 3 nights tops and only if I'm in extreme penny pinching mode. If you can spare an extra 10 bucks a night, there simply are better options that will at least offer you some degree of privacy.
The value's there if you literally just need a place to sleep and shower and can sleep in ghetto sleeping arrangements. If you want anything beyond that, this is not the place for you.
