Get the passport pass when in Andorra. 50% off on 3 museums of your choice including this one. We came an hour before closing, my hack when visiting museums..It’s the time best to visit. Less people. For 5€ you get the audio guide. We did the tour for about 15 minutes. It’s just a big house. A lot of rooms are not accessible. Toilet was clean though. If you have 5€ and 45 minutes to park, walk to get there and visit around..Come here. You also get to see the municipal building adjacent to the house, built in 2011. Architecture was pretty nice. The view of the city from the house property is good too, but you can get this view from the trail Rec del Sola too, and it’s free.
