The couple who travel the world house sitting
https://edition.cnn.com/travel/article/couple-travel-the-world-house-sitting/index.html
What is difficult about house sitting is to find out
friends who are just away from home when we want to visit. And, even if we find a house where its owner is away, we don't know how to keep the house. For example, we don't know how often and where we should keep clean and don't know how often we should feed animals.
It would be troublesome for me to travel by house sitting.
