If you want a great value in the heart of the city center in Prague, I highly recommend Ondrej’s place. It is a beautiful old apartment that sits atop a cafe, if you like unique places this is one for sure. It is super easy to get to the metro from the apartment and there are several restaurants, cafes, and convenience stores all within a few minutes walk from the apartment. After staying in some smaller apartments in Europe you will appreciate the large space of the apartment - the high ceilings were quite unique to most places I’ve stayed.
