http://realty.vz.ru/article/2009/5/13/713.htmlnames Moscow hotels the World's No. 1 most expensive, at USD 200 per night on average.
Compare that to USD 60 in USA, USD 100 in Switzerland, and USD 115 in London.
It's not just lodgings per se though, but food and products, too.
An average cup of coffee in Moscow is 1.5 times that in Rome, 2x Berlin and 4 times more expensive than coffee in USA.
N.B. A retirement pension in Russia is hardly more than USD 100 (one hundred dollars) per month in the best case.
The best thing you can do in this situation is, I guess, start selling coffee unless you can afford to own a hotel.
