Things to see in Moscow in 4 days?
Hey! It shouldn't be too cold at the end of March. Depending on your interests, there are plenty of museums & theatres in Moscow. Yasnaya Polyana isn't a bad idea at all. But, personally, I think you would be much more impressed by visiting the historic places along the Golden Ring of Russia. en.wikipedia.org/wiki/Golden_Ring_of_Russia
