Pepa&Petra's apartment in Zizkov is a cozy, efficient studio which acts as a comfortable and inexpensive base from which to explore Prague if you don't need to be in the thick of it. We slept well, enjoyed the A/C on a string of hot days, and made ample us of the twin Poangs to rest our feet after long walks. Public transport to and from the city center is easy, with multiple modes nearby - including a quick bus to the Old Town right downstairs.
Pepa went above and beyond, particularly with his communication and flexibility around our move-in date and time, which changed numerous times due to the circumstances of our trip.
Be sure to try Noodle Bay - a wonderful Vietnamese restaurant a couple of blocks away - if you're Czech'd out in the meal department, and Kafe Na Schodech - a tiny little cafe nearby with a superb barista and smooth coffee - before you head out to explore.
