Innovative Paris and almost PCR machine...

My stop over in Europe started in Paris. I stayed here with Irena, who is truly incredible host. Some months ago, I have been in Paris with my lab mates: Madina, Drago and Dennis. And thanks to the great guide, Dennis, we managed to cover many touristic attractions in Paris. Now I try to travel on the shoestring budget and I decided to skip the touristic attractions accept visiting amazing Norte Dame and of course the most important lab in Paris,.... Irena one.
