cannot find a place on TMB loop trail in Italy by address

I have the following place by address and try to add waypoint in Gaia GPS map on my laptop. Not work.

Chalet Svizzero Hotel & Restaurant

The address is: SS26dir, 11, 11013 Courmayeur AO, Italy

I have the similar problem with searching by address of several other hotels along TMB trails. I doubt if I can utilize Gaia GPS map when I hit on road in June, even though I already paid the membership. Thanks for any tips!
