An old building in a great location, but you get what you pay.
The common areas were not clean, there was a thick layer of dust (really) in the living area, the bathroom, the balcony etc. It seems that usually only the rooms are cleaned.
The room was good for the price, internet, comfortable bed, a desk and a large closet, you'll get a key to lock your room, but the balcony door can be freely open from outside, it has no lock, so your stuff is not safe at all.
In conclusion, the location and the room is great, but the apartment needs cleanliness, maintenance and love.
