Tech geek, recovering engineer, and startup guy.
Mike and his company were three nights at my apartment in Rio and they were wonderful guests. I live far away, so we used airbnb and e-mail, and the communication was very good. Mike is really kind and polite, leaving a very good impression on the person who takes care of my house. I was told It was so clean and tidy when they left, you wouldn't say someone actually stayed there.
So if you get a request from Mike, don't think twice, he is the dream guest, highly recommended!
