Although it is of course worth the visit, even in Covid times, there are too many people. You often have to wait in line to get into the various rooms. You can book tickets in advance for a specific time, but even then you have to line-up and wait to get in. It is not well organized and people were confused about which line to stand in.
Also, your ticket might not automatically include a visit of the gardens, on some days you have to pay extra.
