Nothing wrong with the area. However -- for me, who also prefers to walk just about everywhere, it is less than convenient to do so. A few years ago I stayed in an apartment overlooking the southwest corner of the gardens. Google map walking distances from the location you're thinking about to various sights you want to walk to and judge for yourself. When we stayed in that apartment, prior to the trip, I mapped out some things and thought, no biggie.... but once there and dealing with it (and my tired self/feet) each day, I felt it was too far away from the river to be as convenient as I might have liked.
