The hardest part of the visit was navigating the city streets and finding parking.

It was raining lightly so we had to be cautious walking up the cobblestone ramps and stairs. But other than that, the rain is not too much of a deterrent because you can spend a lot of time inside the various museum rooms and even stand under arches and such while taking photos in the various courtyards.

This visit was a last minute addition to our plans so we only had a little over an hour to go through it. I think we could have easily spent 2 or more hours there.

A word of warning, check the website the week you are planning to go there. If there is an early closure to the public that week, they communicate that as a pop-up message on the homepage. You don't want to go through the trouble of finding a parking space, only to find out the museum is closing in less than an hour.

Also, as far as I could tell (there were some places blocked off to us as they were setting up for some sort of event) The only rest rooms were 2 port a potties right after you get inside the castle proper. If you think you may need to go within the next hour or so, use it now. You don't want to be on the other side of the castle and have to retrace your steps a couple extra times. Especially if you have a limited amount of time.
