Pro: great location, nice staff, kitchen available on premises, good value, plenty of bathrooms in the corridor to choose from so you never had to wait for somebody to come out.
Con: the furniture was very old and with a lot of wear and tear, the bed was on a metal frame and you could not even turn at night without it making plenty of noise. One day we found a cockroach on the room wall next to the garbage bin (they did not seem to have an infestation though, it was the only roach we saw during our entire stay). Most of the kitchen utilities were pretty dirty and seemed unsafe to be used, e.g. one microwave oven actually had a hole in its back from all that rust, you could see the back wall when it was open.
Overall: value and location might make up for the cons, if you are not a picky traveler
