I recently spent 9 nights here and found it to be a well maintained, chilled environment. Karla was always busy keeping the place very nice and clean and was very pleasant.
The room I stayed in was a little noisy due to traffic and disrespectful others staying in the room.
I would suggest that it is well enforced in dorm style accommodation all are made aware that one must be respectful of others and not wake the whole room up night after night at early hours of the morning.
The only other down point is that it desperately needs another bathroom as one is not enough to accommodate the numbers.
But over all I would recommend karlas place to anyone that is looking for a exceptionally clean and pleasant place to rest their heads.
Best wishes. Happy travelling
