I believe that its a combination of a great opportunity to meet new people and explore new places and its culture! Myself, have not tried couch surfing yet, although got some really nice recommendations from my friends. So surprise me ;)

Will help to maintain the place clean while I am there, cook meals and etc. Ultimately will try to make this time most comfortable for them. I will be happy to hang out together and have a nice conversation. Also my host can expect a little surprise from Russia :)
