Location is perfect. Staffs are nice and helpful. Breakfast is good. But, hotel of Regina, at Madrid, has better breakfast.
I think what Hotel of Jazz can improve is therir breakfast. For example, some meats are over-burned and alsmot black-dark color, not healthy. Also, they may delay the breakfast hours to 11:00 AM (not 10:30 AM). Most hotels at Spain has the breaksfast hour up to 11:00 AM. Compare to Hotel of Regina, Hotel Jazz doesn'y have many meats choices.
Anyway, breakfast is good but not great.
Still, overall, Hotel Jazz is a great hotel.
