About what you'd expect.
Cleanliness: 10/10, everything was sparkling clean.
Location: 10/10. Very hard to beat.
Amenities: 7/10, sink is in a weird spot and can't put toiletries down easily, making putting in contact lenses a bit of a challenge. Could use some tissues in the room too, I had to go get my own. Wifi is fast enough but chugged a little when watching 1080p video at peak hours.
Quality of sleep: 6/10, as a sound-sensitive light sleeper. The radiator squeaked, and made lots of noises that constantly woke me up. Since the walls are thin, I could only sleep when the latest neighbor went to sleep and had to wake up when the earliest neighbor woke up. The bed and pillows were quite comfortable though.
Other: When I was walking into the room, I was greeted by a pretty strong smell. It wasn't a bad smell, it just smelled kind of like an old building (which it is). It only took a few minutes to get used to, but it is very noticeable when entering the room.
Also the elevator is very old, kind of a nice novelty to ride once but I just took the stairs after that.
I would stay here again for a short-term stay, but I would avoid it for a long term stay due to the difficulty of getting a full night's rest with the noise level.
