Don't even think twice about it. Tell them to double it at least. This country is really expensive and 11,000 is nothing monthly. When you come from the West you have to remember you're going to sacrifice to live here so there has to be a benefit to make it up, which is usually the money. 11,000 you won't be saving anything. A decent apartment will run you over 6,000 and a car will cost you at least 3,000/month if you finance or rent.
