I visited Russia in 2013 and 2014, and there were a lot of gritty places, but availability of modern retail shops, goods, etc. was basically the same as places in Europe at that time. My kid travelled there last summer and said the sanctions are having an impact, but a lot of it is on the order of, for example, McDonald's changing the sign outside to some knockoff brand and sourcing their ground beef and packaging from somewhere else.
