生きる→住む、暮らす is better. 生きる sounds a bit like to be alive or to survive. ための場所 means "just made for that". How about 〜たくなる場所？(the place that makes me want to...) 年寄り→お年寄り is more polite. ありますis for non-living subject.いますis correct. 住んでいます is maybe more natural. 退職後に暮らしたくなる素敵な場所なので、お年寄りがたくさん住んでいます。

Hi Alexander, It would be perfect if it was 「あります」→「います」at the end of the phrase. 「ある」and「いる」are a bit confusing predicates, but not complicated. 「ある」is used for the existence of inanimate objects including plants. For ex, 「あそこに銀行(ぎんこう)があります」「ここに花(はな)があります」 「いる」is used for the existence of animate objects. For ex, 「教室(きょうしつ)に先生(せんせい)がいます」「いすの上(うえ)に猫(ねこ)がいます」 So, the question phrase would be 「年寄りがたくさんいます」, and in many cases, those elderly people have to be respected, so it would be more suitable to say 「お年寄りがたくさんいます」. If you’d wish to make this phrase in more formal way, and also hoping it’s interesting for you, 「生きる」→「生活する」would be recommended. 「生きる」sounds like ‘surviving day by day’, so ‘to live’ would be translated more like 「生活する」. So 「退職後に生活するための素敵な場所」will be acceptable. To modify 「素敵な場所」, natives may say like「退職後の人生にとって素敵な場所」; the verb ‘to live’ will be converted to the noun ‘life’, but the meaning remains still. 「～にとって」means like ‘for someone’, so the phrase ‘it is a nice place to live’ could be converted to ‘it is a nice place for retired people’s life’ as a Japanese translation. I sincerely hope this would be a help, but if you’d feel that’s too much, please take my apologies and just focus on the way of using 「ある」and「いる」. All the best!!!
