Overall, our stay was fine. It works well for a place to sleep at night while you spend all day outside exploring the city. The price is great, but that's because you really lack privacy. We were woken up by fellow guests at 6am when they took a shower. You can also hear every time someone opens/closes a door -- not great for light sleepers like myself. You may also run into the situation of having to wait to take a shower if the bathroom is occupied.
One big issue is that when we got back one night, the key card would not let us into the building. Thankfully, we rang the bell and another guest let us into the building. Not sure what we would have done if they hadn't let us in because it was past midnight.
