I am familiar with AirBnBs in the US. And I have stayed at five thus far in Europe. While they have all been good Jaroslav's is undeniably the best. His facility is the Ritz Carlton of AirBnBs.
And he is a gracious and thoughtful host despite the fact that he prepares for virtually any and all circumstances. I wasn't planning on staying in Prague as long as I did but the facility was so nice I figured, why not?
