Question about senior citizen services/assistance (what else can i do)?

Its a bit of a better late then never thing. I recently paid a visit to my 90 year old godfather (cutest little old fart lol). I was appalled and shocked at how and where he was living : *( in a dangerous area living in a referbished hotel surrounded by junkies. I took him to lunch and bought a couple sweaters (its gets pretty cold) anyway i stayed for a good chat in his apartment (horrible horrible) there is this one man across the hall (he is am OBVIOUS drug user a big guy too, he just walked right in asked to use his phone and took a lemon out his trashcan wtf!) anyway I didnt want to say anything god forbid he try to hurt him later (which he told me that scum had ruffed him up before) but i made sure he knew that i would be around from now on. Anyway i could not sleep thatr night, i cried and cried its awful how people take advantage of the elderly i mean he his old but sharp as a tac but he is so kind its hurting him badly. but he has no medical problems as far as i know

! No problems other than a bad back. He can live on hs own. I need to get him out of that ****hole. I called senior services to help him try and move (he does get pension and SS but everyone around him takes advantage of him, his heart is too big) but is there anything else i can do to help??? I am so scared for him hes 90. I love him very much and i wish i would have seen him sooner other than the family parties etc.. he has no family here other than my family (hes not a blood relative but that doesnt matter, his own family doesnt even come around!!!)

Please help if you know what i am going through or anything else you would suggest. I plan to check up on him here and there. The senior services said they would call him and to help him move after a home visit since safety is the issue. No one should live like that especially a man his age : (
