Travel Advice Needed for Mobility Impaired

My mother has MS so I realize how difficult a lot of areas can be. I'd rank Chicago as pretty accommodating to those with mobility issues. Many train stations have elevators and all public transportation is accessible. I assume by tall buildings you would prefer to avoid skyscrapers, so I'd avoid downtown areas like the Loop. I think Lincoln Park might be nice, with plenty of areas for shopping and quick access to major museums, etc and it's safe. As far as lodging, there's a historic hotel called "The Belden" in Lincoln Park. It's not exactly townhouse style but it's not a skyscraper either,so you might like it. From most of Lincoln Park you can access outdoor areas (including the Park and Zoo) as well as trains/buses to downtown. If you have any other questions, please post here and I'd love to help out more. You are definitely visiting chicago at the perfect time of year!
