Sasa was a perfect host, he met us at the flat, explained where everything was and how to do everything in the neighborhood. He even offered to give us a small city tour! (since we had our small baby with us, we preferred to go alone at our very slow pace, but the offer was much appreciated). The second evening we had a glass of wine with him and his girlfriend at the wine bar downstairs - very very pleasant! When we left, he carried our pram down 4 flights of stairs! Would recommend staying there, especially with kids, the neighborhood is calm and not touristy, it is close to the Petrin Hill with brilliant views of the old town and Hrad, and the apartment is enormous, so plenty of place to hang out when the kids go to sleep.
