[Likeguslee]

If there is a telephone available and convenient where you stay at, please give me the number, and I will try to call you

Or

If there is a telephone available and convenient at the place you stay, please give me the number, and I will try to call you

[MrPedantic]

I think I would say:

"If there's a telephone where you're staying, give me the number, and I'll call you."

The two halves of the original sentence seem a little inconsistent: the first clause seems to relate to future knowledge (when he gets there, he will discover whether the telephone is available and convenient), whereas the second clause relates to the present ("give me the number (now)").
