Ondřej was very welcoming and left lots of information for stuff to do around the city. The apartment itself was pretty amazing and in a super lovely location - very connected for public transport but we found we could walk to most of the sights. The only issue was that, as the ceiling was quite high, it did get a little cold (though what do you expect from Prague in Winter?), though once the radiators were turned up a little it felt cozier. We'd definitely go back! :~)
