Agenthy did a good job keeping the place clean, but it's in an old building and comes with old building problems - leaky tap, a toilet that wouldn't flush properly due to low water pressure, a bathroom that smells slightly of sewage, the bathroom sink that regurgitates old dirt and hair when you drain it after washing your face - leading to the overall feeling of shabbiness.
The windows are all single pane so you'll definitely hear noises from the street and the courtyard. Generally it was quiet late at night, although some noises from upstairs did wake me up occasionally.
One thing that surprised me was that right outside the bedroom was the building corridor, and the bedroom window opened to directly to that. Which means that you need to keep the curtain closed at all times if you want privacy. That wasn't clear from the pictures.
The kitchen was clean and well equipped and it's very conveniently located. But at that price, I'm afraid to say I don't think I'll stay here again.
