Unfortunately, I never hosted anybodoy because in Japan, I live with my parents.
When I finish my travel and go back to Japan, then I think I will live alone and I can host CouchSurfers at home.
If you wanna take a look, here is a link to my CouchSurfing profile.
Note:
CouchSurfing is the website that I use to travel around the world. Concept is, "My couch is free at night so If you just crush on my couch, you can sleep on my couch for free."You don't need to pay anything. So, you save some money and you can meet up a either local or traveler from all over the world. I love CouchSurfing for many reasons. Of course I save some money so I can travel longer. But it's not just that. I meet a locals who know about the town so I can get to know more about the town, food, place to go, things that I cannot miss or any kind of event in the town.And, there're so many cool people on the CouchSurfing!!
There are some people who had a bad experience with CouchSurfing. I never had a bad experience and never heard a bad story from other CouchSurfers I met on my travel.
