Directly around this area are many old rundown large social housing/apartments, between the garden areas of the new buildings
What exactly do you mean by that? Townhouses are normal and social housing is not negative per se – I even find affordable housing positive, my grandmother lived happily in such housing for decades; nowadays it is a gentrified district with absurdly high rents around the social housing, that's when 11ant hits the nail on the head.
On the other hand, I find it important to feel comfortable in your neighborhood. And everyone feels that subjectively. For example, I would never move somewhere where the neighbors look at you weird because you are not from the town or you don't understand anyone because you speak High German and don't understand Bavarian dialect.
How is your feeling on site? Like if you really walk around there during the day? (If you are currently overly skeptical, also in pairs?) Talking to neighbors?
I would recommend that too. Just go for a walk there, get into conversations. That makes sense anyway, also to experience other things on site: noise from the street and co, walking accessibility to important shops, public transport schedules, and so on.
