I actually lived (rented) off of Calle Cristobal the past 1.5 years. In fact the place I rented is now on the market and NO WAY would I pay the prices they were asking. Not even 10-15% lower. asianautica has done an extensive amount of researching listings in mm and sorrento valley and has keen insights in the area there. As someone who used to live there and still works in Sorrento Valley I know it well also. Try to hold off if you can. I think some serious future foreclosure activity will happen. There is already CURRENT forelosure activity there right now.
