PhD student looking for accommodation for entire July and August in Warsaw

I just need a place for the basic needs. Would appreciate not to be disturbed when studying or working. For the most part of the day I'll be in the University. As for my personality, I'm a quiet and educated person. I don't drink alcohol nor smoke, and I prefer quietness and intimacy in order to stay focused on my duties. I prefer a tidy and clean space to study.

I enjoy conversations with other people and I love travelling so it would be nice to learn a bit from Poland's culture. I love playing the piano and composing music, which is my second profession. I'm not looking for the perfect place to stay, but I would like it to meet at least a few of my expectations.
