Mendoza renting an apartment

Hello, I am returning to Mendoza and would like to rent an apartment for one week in mid-May. This is something that I have done many times in Buenos Aires and there seem to be lots of agencies, but I'm having a hard time finding an agency to rent from in Mendoza. Any suggestions would be much appreciated.

Also, if you have recommendations for a guesthouse with use of kitchen, that would be terrific too.

Thank you.
