I will be staying the full week in Chicago for the S4SN and the SfN and as it happens I have a really nice flat in South Wabash Ave, which is within 15 Minutes walking-distance to McCormick Center.
Originally a labmate also planned on going and staying there with me, however, he will not be able to make it, which means, I have an opening for a roommate who also plans on staying at least 5 days.
You will be having your own room and bathroom. We will share kitchen and living-room, a gym can be used for free (for those sports-aficionados out there) and yes, it has WiFi
If you are interested just send me a PM, the price is very reasonable and I can send you the details via PM.
