Let me introduce myself.

Hi. My name is Sena. I am Korean.
These days ("Recently" makes it sound like a past event) I host international guests at my home through AIRBNB.
It is very interesting to me.
Even though ("Even" adds information you would not expect to be included, while "even though" adds something that's in contrast (i.e. opposite of) the main statement) my body is in Korea, I can feel like I'm overseas.
I like traveling. But because I have a job (maybe "but while having a job"?), it is difficult to go travel. More natural: ... it is difficult to find time to travel. 
So for now I am satisfied to host guests at my home.

My English is not good enough to have conversations with the guests. I wish to improve my English more.

Isn't there a person who wants to be my English friend here? I can also be your Korean teacher and friend. ;-)

I have a teacher already, but we could be friends if you wanted. :)
