There are two air conditioners in the apartment, one in the living room and one in the hall. Both was switched on during daytime, but we felt the coolness it in the hall only. So, the bedrooms were a warmer than we wanted them, and we couldn't open the windows because the traffic is very noisy on that side. It is advised to use earplugs during the night.
We have found disturbing the followings: the wardrobe locks in the bedroom are very much worn out so you can open and close doors after a few try, the safe could be used only with the emergency key, and not with the combination lock, and the pillows in the glazed balcony were too thin, so the benches were uncomfortable, so we couldn't really enjoy to stay there.
