I can highly recommend Robs and Pavels flat. It is very nice, clean and has all you need. Pavels Prag introduction, Tipps and the little self-written travel guide of them were very helpful. They even offered s.th. like a service no. during our stay in cad that we would have needed any help or guidance, which we luckily didn't need.

Thanks guys!!! And for all the others:
You should stay there!
