In general the flat is nice and comfortable. However if the view from the window is very important for you then you might not like it. The host is friendly and ready to help, so if you need any help or information don't hesitate to contact him.
The district is cheap and looks specific. If you don't like aesthetics of old and broken houses (as I do) then again you might not like it. On the other side it allows to see the "real" life on the streets and it seems to be safe. Also many landmarks are very close to the house.
