I used to meet at a local library for transactions and we would get small studying room (free). It is personal, private, but still public enough to avoid violent theft
It is good to hear that you have the opportunity of a private discussion room where you can handle all the matters related to trading in your personal way. Trading in todays world has become a difficult task just because the privacy o the people is much vulnerable to be breeched by the hackers. So I think that everyone must seek some sort of safety measurements to avoid a loss.
