Hi guys,

I am 23 years old going down to Chicago for a full week on business. I'll have a rental car so I can get around to the office. I like modern and luxury hotels but must stick with Marriott brand. Looking at my corporate travel website I can stay at the following hotels:

Residence Inn Chicago Downtown - 3 star
Renaissance Blackstone Chicago - 4 star
Renaissance Chicago Downtown - 5 star
Courtyard Chicago Downtown (River) - 3 star
Chicago Marriott Downtown - 4 star
Courtyard Chicago Downtown (Magnificent Mile) - 3 star

I like to go eat good food and do a bit of shopping so location is pretty important. What do you guys recommend in terms of best location, most modern or renovated and best overall hotel?

Thanks so much!
