I'm giving this place 4 stars on the basis of the garden. The house is an old mansion and as such is impressive (the mansions on either side of it are still occupied), but really you're here for the garden. This is a museum of decorative arts, but other than the house itself and some loaned paintings on the walls, there are only three rooms that contain real displays.
The first floor basically shows off the architecture and tells you a little about the history. The ceilings are nice (do look up) and there are a few pieces of interest (the library features a chair suitable for making best use of space in a corner). Note the blue and white tiles in the built-in cabinets next to what I think was the kitchens (used today for museum events so you can't tour them).
On the second floor there are two rooms with what I'd consider a decorative arts display, and one stained glass window displayed inside next to the elevator. One room contained decorative art from the period: ivory carvings, including one very impressive tusk carving, some netsuke, and two "doctor's dolls," which allowed modest Chinese women to show the doctor where it hurt; and a porcelain plate showing Louis XVI and various ladies of the French court.
The other room with decorative arts was a temporary exhibit of metalwork (teapoints, salt and pepper shakers, decorative sculptures and panels). There were also a couple of rooms dedicated to wrought ironwork done by the gentleman who did the ironwork for the house, which were very interesting. There are several panels showing the process of making wrought ironwork, including a cabinet with a large repousse piece that you're allowed to open so you can see it from the back and read explanations of the techniques used to make it. In the same room there's also a large panel "masterpiece" which won a prize at a World's Fair.
The bathrooms included an early example of multiple shower heads in a shower, and a few more pieces of porcelain.
Now to the garden...it didn't contain a lot of showy flowers (irises, roses, some impatiens and other annuals; a few tiny pots of herbs on the landing).
The garden and the building are based on the concept of a Roman villa. It's gone a little wild (funding has apparently periodically been a problem) but the vista is beautiful and it's nice to stroll through. The architect's intent was to make Lake Michigan serve as the villa's Mediterranean and it does.
You can just look at the garden, or actually go out in it. There's a tram (broken when we were there), or 100 wooden steps (with landings) to take you down to the bottom to look at the statuary and plantings.
Street parking is 1 hour max, except Saturday/Sunday. It probably won't take you an hour to do the place, so that works.
