We were brought here on a private Prague tour of supposedly secret locations. The tour was great, the garden beautiful. But it's a garden. If I lived in Prague, I'd go there regularly; to sit, enjoy the roses and the calming atmosphere (sans tourists ;-) but without our tour guide telling us interesting things about the monastery that owns/maintains the gardens ... well it would just be a garden, now wouldn't it. And not the most amazing one I've seen either. But for city center: very nice.
