Nice museum spread over 4 floors (there is an elevator by the way). It took us a little big over 1.5 h to see the exhibitions (paintings, jewelery collections, ceiling paintings, antique household items, modern art pieces). A full price ticket if you are not eligible to any discount costs €7. It seems to me that the entrance is free the last hour before end of business. A couple of famous paintings (at least 1 of Goya's) are on loan until the end of January 2022 so you won't be able to see them.

7€ entry for adults. Very good museum, a wonderful collection of paintings, jewellery, armour, tapestry, brass and more. Also, there is an adorable ginger cat that sits outside and welcomes the visitors.

Intimate museum in the collector’s home. You can get up close with pieces by Goya and Bosch without the crowds. Hidden gem in Madrid.
