I wouldn't bank on being able to easily get a luxurious two week rental during the on season (now until around January) in a nice area all willy nilly at the last minute. In the pre-furnished rental market, $1000/month does not go very far unless you are willing to stay outside the wealthier/nicer areas (Recoleta, Palermo, Puerto Madero etc.). The nicer areas are going to run closer to $2000/month for a two bedroom and you won't be getting any discounts on an eleven day stay. If you are only staying eleven days you could save yourself a lot of headache by staying at one of the several nice bed and breakfasts in Palermo that will only run you about $40-70/night. The service quality of some of the rental companies is unpredictable at best and some can take anywhere between two days and forever to respond to your e-mails/calls.
