Swiss chalet

This vintage postcard has the date "18 Juli 1929" on the top and the postmark for the same day across the top.

The postcard shows a Swiss chalet in front of a large forest, and a young boy standing in a meadow in front of the building. The message on the back is written in a very neat hand with fountain pen, but is written entirely in German so I'm unable to translate it properly.

The postcard is addressed to a Professor Grunder (?) and seems to be sent to Brusala in Sweden, but it also mentions Mendrisio which is a region of Switzerland. It also has a green Helvetia stamp on the top right of the postcard.
