Connecting to RB2011 Router to ISP Router by WiFi

Hi,
I´m a little dusted configuring mikrotik routers.
I have a RB2011UiAS-2HnD-IN router. I need to connect it to the ISP Router so i can use the internet of the building.
Because this is an operating bulding, they won´t let me do it it by wiring, They want me to connect the RB2011 to the ISP Router by WiFi, like a client.
Is that possible?
If it is, can you help me with the steps how to do it?

Thanks in Advance

Possible…yes.

I read the blog.
It mentions a wired connection to the hotel internet. I can´t do that.
It has to be from router wifi to isp wifi…
