Regina's apartment was perfectly located for touring the Castle District. The home was immaculate and had a large, spacious shower as well as a great kitchen (with ample pots, pans, etc.). The neighborhood is safe and has a number of restaurants nearby. I recommend staying here. You can walk to the Castle, but Old Town, the Jewish Quarter and New Town are probably better accessed by tram, metro or bus (all of which are very close to the apartment). Regina lives in the adjacent apartment and was a lovely host.
