My brother went through this as well with my dad. Dad had to give up the home he actually built himself to go into a home. He had broken a second hip and as I was not living in the US, could not come and care for him, so he was in a convalescent home and got MRSA in his heel! So he was wheelchair bound after that as he could not put any pressure on his foot for months till the sore closed. By then, his AMD was totally bad and he could not get around even if he was not in a wheelchair.
So... my brother found him a place in a great home, near the sea. He visited him every day as, like you, it was just minutes from his work. I was getting a phone call here in the UK from dad almost every day. (He had internet access but could not see to use his computer any more sadly).
My dad was a very social person, and after 6-7 months began to enjoy the company of the staff, and they liked him. As did the ladies LOL, as he was only one of two men. He played piano there all the time. After about a year, he said to my brother that he hoped there was enough money to keep him there as he really liked it. My brother still took him for rides and went past his old house, and other places he used to to with my mother, but he knew he was in the best place possible. He had three years there. That is about average for a nursing home resident (not cast in stone...just an average).
Looking back I often was a bit 'inconvenienced' by his calls because of the time difference (midnight or later!) but kept telling myself that he raised me and loved me, warts and all, and he was doing the best he could with a new and strange situation. If he had been coping with dementia, I am sure this would have been more difficult if not impossible for him to settle.
I still miss him and wished we had gone a month earlier as he died the month before we were to travel to see him.
