Let me start by saying I don't usually review hotels I stay in, because the vast majority are simply 'ok' and I can't find the enthusiasm to spend time on a review. However, I've just got back from a week's stay in Hotel Lincoln and was moved to say how good it was.
It's right next to Lincoln Park in a leafy, safe area of the city, and getting downtown is easy either by bus, which stops right outside the hotel, or using the CTA - stops for the red and brown lines are both within easy walking distance. So the location could hardly be better.
When we arrived, check-in was fast and painless, and the staff were friendly and helpful throughout our stay.
The room was perfect for our needs. The king size bed was really comfortable and the bathroom was clean, with a nice powerful shower. I slept like a log every night.
The rooftop bar was a nice surprise, with great views across the city. It was pretty rammed on Friday and Saturday nights, but we managed to get a table without any trouble. The drinks aren't cheap, but they're certainly cheaper than lots of the downtown bars.
I suppose if I was being really picky I'd say it'd be nice to have a breakfast option, but there's a cafe in the hotel lobby and several other great places to eat within a few minutes' walk so that wasn't a problem at all. I'd recommend Elly's Pancake House, a couple of blocks down the road.
If I ever go back to Chicago, this is the first place I'll be looking up.
