The inside of the apartment was fairly good, but not entirely safe. The balcony was next to a public place window, the facing apartment belongs to a restaurant that holds parties every weekend. They played loud music till 1-2 am and used to smoke on the stairs, in front of our door. Also, the building door was open to the public!
Moreover, the next building was a night club and they play heavy loud music till sometimes 4 am and their crew then clean it till 7 am. We could hear their voices.
