Is it possible to live and work in different cities?

I did it for 18 months. I was selling industrial equipments by mail, phone calls and visits to overseas customers. I only came to the factory once or twice a month.
But I realized I annoyed my colleagues in R&D as I had to phone them often to get technical information. It is one thing to drop in at their office and have a technical chat. But calling them is another matter. The noisy ring at the wrong moment and the impossibility to make explanatory sketches are not good for communication.
So, I had to go back to the office.

Hundreds if not thousands, both Poles and foreigners are traveling each week between Warsaw and Wrocław, back and forth. You should have no problem.
