Dear Masha,

You should try Al Dana Club as they have nice indoor clubs and the Reception Counter there could help you get a decent female tennis partner as well.

Alternatively try Qatar Tennis Federation as a lot of people play tennis everyday over here. (No Indoor courts).

The Reception counter (440 9666) here would be able to help you too. Just give a try.

All the best...

Remember, its not the years that count, but the life in the years lived.
