Super lovely, best located room! Quiet, well working heating, confortable bed and sofa. No problems at all, I can reccomend it! Don't miss the great coffee shops in the proximity and the farmers market (with organic food) (Nám. Jiřího z Poděbrad, with a crazy church building!) And the sneaker shop "botas 66" (Křížkovského 18)!
And thank you for the interesting map of Žižkov :-)
