After you've "done" the Prado with its overwhelming collection and swarms of visitors, go to the Sorolla Museum. It's in the artist's former house/studio and is full of his lovely, accessible paintings. The well-maintained gardens were the artist's pride and joy and featured in many of his works, so they deserve some time as well. I also enjoy the furnishings. The entrance price is very reasonable, something like 3 Euros. This place is a true find that I first visited in 1985 and have been recommending to friends ever since. Reachable by Metro: Rubén Darío on the green line; just walk up La Castellana to General Martinez Campos and turn left. It's a 15 minute walk at most. Tip: After my most recent visit, I had a very enjoyable lunch right across the street at Al Alba de Madrid.
