Have not been toMadrid in many years. Is this a hotel worth visiting? Any good private tours you can suggest?

Madrid has changed somewhat over the years, and continues, and all for the good! The Hotel Círculo Gran Via is now a Marriott Autograph Collection. The area is busy, but nothing to shy away from.

For a private tour, check out Madrid Museum Prado Museum Private Tours. They offer a good selection of private tours with experts. The prices are also decent.

Don't forget to check out Maribel's Guide to Madrid.

I id read Maribels guide---great!
