Since we were in Malaga, we decided to see Picasso's work, so we visited.
On the day we visited, there were quite a few people who hadn't purchased tickets in advance, and they were unable to enter—it's a very popular tourist spot.
It's located in the city center, so access is good.
Picasso's sensibility may be difficult for the average person to understand, but I think it's worth seeing at least once.
