TRY THIS Everything is fine with your code just you have to group by only guest_id, if you add nights also in group by then COUNT & SUM will be calculated accordingly by grouping data using both the columns:

select guest_id, count(nights) , sum(nights) 
from booking 
inner join guest on guest.id=booking.guest_id
where guest_id in(1185,1270)
group by guest_id
