For the price, I cannot complain: great location, private (if tiny) bathroom, good housekeeping (clean and new towels, a shower curtain which doesn't smell of mold, etc.), high ceilings making for a fair volume, up-to-date Sharp AC, LCD TV, hot pot, coffee, and tea.
I was in a second floor room facing a ventilation shaft, and thus spared traffic noise. However noise transmission in those old buildings will disturb light sleepers (I brought earplugs having read previous reviews :)
The wifi signal in my room, located one floor above the reception, was very strong.
