Hi Julian,
There aren’t really any islands of foreigners in Chengdu so you should be okay there. Popular neighborhoods in that area are Zongnan and Zongbei, both within walking distance of the consulate. Tongzilin is a little further away but also walkable, and so is the Yulin neighborhood. There are some new developments going up on the consulate road, literally next to the consulate, that look very nice also. Not sure if they’ve opened yet, though.
