Great Airbnb & host. :) Location is great in Praha 2, New Town with lots to walk nearby (if it isn't too early or late, of course).
One thing that can be improved greatly is the check-in -- while my experience was not bad especially as a solo traveler, the room is inherently difficult to finally find & settle into.
Zeb & Josef are great responsive hosts, and are nearby for any assistance. For travelers arriving late or not up to an adventure, the keys may be a bit difficult to navigate, and more so, the hallways of the apartment building complex has REALLY dim lights, if not on at all. In the evenings it can be quite creepy really.
