Moscow is one of the more expensive cities in the world; prices here range from similar to Newport Beach, CA on the low end to Central Park East, Manhattan, NY on the more expensive side. That's what happens when you have a population of 14 million, with more billionaires than any other city in the world, and a housing shortage that still hasn't caught up from the collapse of the USSR. Needless to say, finding an apartment in our price range which is large enough for a family of five is going to be a challenge.
Some people are telling us to look for a two room apartment (not two bedrooms, two rooms…) which is way to much like just continuing to stay in the guesthouse, but paying for the privilege. Not really a viable long-term option. There will be tradeoffs between size, amenities, quality of repair, commute, and of course, price. Wish us luck!
