What's the appropriate response to finding out someone has a tiny house?

Let's say your friend invites you over to see their new home. You pull up in the driveway and find that it's an off-grid 500 square footer. Not quite the house you're used to. What's the appropriate response? Do you say, "Oh my god that's so cute." Or, "Really, you expect to entertain me in this little thing?"
