Russian (and Ukrainian) cities top the list of European cities with the lowest COL, comparable to many Third World countries, but without the sweltering heat and non-whites. It's appealing as a summertime geomax destination, though the hassles of getting a visa and having to carry large quantities of cash into the country would make it a challenge to visit. Interesting how Latin America is the only region of the world (apart from Central Asia) that Russia universally gives 90 days visa-free entry to.
