Apartment or Room in Roma Norte, Mexico City

Hello! Looking for an apartment or room in JAN/FEB - also open to apartment swap in Chicago! Warning: it will be cold :) - when? starting in January (4th? 11th? Flexible!) - how long? 4-6 weeks - where? Roma Norte, Condensa, or nearby so I can commute to Roma Norte in <20min - budget - Under 12000 would be nice, but I am flexible depending on room or apartment and quality/location
