Hi Lisa!
I enthusiastically recommend Windy City Urban Inn ###-###-####), which is just off Clark St. on Deming and very convenient to everything on the North Side. Mary Shaw is your hostess and she is a blast. If you want other possibilities, I will self-promote shamelessly and suggest my book, "Romantic Days and Nights in Chicago," which has a million fun ideas and a very nice gift for your parents and anyone else visiting or even living here! "Romantic" is in the local travel section of all bookstores -- B&N, Borders, Women & Children First, et al -- and I hope you enjoy it!
Viva Chicago, viva romance!
