it really depends on which place you are going to and who you are going to stay with. I tried the airbnb in Osaka and Hiroshima, the house sizes were bigger than regular hotel room. However, if you are bringing kids with you, I would suggest you to book hotel as it seems to be cleaner to me and safer. you never know how those airbnb owners clean their houses... and if they ever change the bed sheet, pillow cases and etc. a lot of them may just use some fragrant to cover the smell........!
We are family a group of 6 (2 kids and 4 adults) going to Australia Gold Coast.
We love cooking and most of the time we booked villas tho agent. And this time we would like to book ourselves.
