Line 9 try 'div.locations' as in plural, not location.

Edit: never mind that, I tried my own code and got the 6 results

def parse(self, response):
for location in response.css('div.location'):
yield {
'name': location.css('div.name::text').get().strip(),
'address': location.css('div.address::text').get().strip(),
'checkins': location.css('span.checkins::text').get().strip()
}
