Shame on Prado Museum
This museum is a hidden gem in Madrid, don’t miss it next time you visit the town. The Museo Sorolla is considered to be the most complete and best preserved artist’s houses in Europe. The heart of the museum is the artist’s open and spacious studio filled with his works. This should be a no miss for art lovers and garden lovers. It is located in a very elegant part of Madrid.
