It's worth seeing. Yes, it's a free museum in Madrid. Although it's free, it's really worth seeing.

On the recommendation of my friends, I went to visit this museum. It was really good. There were many very meaningful gains.

The Museum of San Isidro is usually okay, because the venue is so big that most people don't feel it when it's crowded.

It's very good. It's always updated. It's very big and rich. Especially those antiques are very attractive to me.

Ancient and modern cultural relics are available, and there are different temporary exhibitions from time to time. It is recommended to visit them many times. Generally, one time is not enough.
