Impromptu visit with no prior knowledge of what to expect - was an hour & half of enjoyable visual aesthetic discovery with considerable "wow" factor with the ornate grandeur of the Lower palace itself. Almost missed Hall of Grotesques leading to inner Marble Gallery & the richly gilded Gold Cabinet which was once Prince Eugene's bedchamber. This lead onto the Museum Longmatt collection of impressionist works of Cezanne, Monet & Renoir & the Palace stables with the medieval & Renaissance art. All this is on the far left of entry hall - where you can also buy entry tix & has the gift shop. "More than Character Heads" exhibition was also really good with amusing bust caricatures. Is 1.5 hours enough? Of course not! But this is all I could spare unfortunately- so it was a whizz through. Visit was prior to Xmas few weeks ago. Cloak room & toilets are in the basement. You can enter Lower Level from the rear street & walk through the back entry doors. I purchased my tix onsite - timed entry but Lower level is not as busy as upper level Belvedere.
