What is the best sleeping bag for backpacking Europe? - best hostels in europe

What kind of backpack is best for backpacker hostels throughout Europe, down, synthetic or hybrid? I have a need or a leaf is enough sleep? In September I will in England, France, Italy and Greece, and travel agency workers are between 10-25 degrees.
