I've studied with Miwa-san for a couple of weeks now and moved up to 1h lessons now. We never run out of things to talk about and always have a good laugh, especially when I try to talk about things way above my level :D. Miwa-san is always supportive and patient, helping me construct the sentences I want. I feel that my confidence in speaking Japanese has definitely improved over the past few weeks!
We talked about topics we both enjoy. It was just like talking to a longtime friend with the added benefit of corrections and suggestions for better ways to say something. I'm already looking forward to my next lesson.
