Does Bulgaria use those letters? Easy is a decent word, but with IDNs coming the market will be more in whatever script is used locally. Russia is a big country so the odds of someone wanting a English version of a Russian word improve. Is this the only way to spell лесно with English letters?
This is not a domain you are likely to sell quickly for more than XX, as Lincoln has said - you might get a domainer to put $20 into it if you convince him of the meanings. A Russian buyer could take ten years or more to appear, but he might pay $500 or more. Might. There are a whole lot of trees in Russia. - Less and less each day, but anyway.....
