I am travelling a last minute trip to the Canary Islands but due to flight schedules, I will have about a 30 hour layover in Madrid. Arriving at 9 am on a Friday and leaving at 4:30 pm on a Saturday. I am staying in the Puerto del Sol area. I am travelling alone, in my early 40's and can get by with some basic spanish. What should I not miss? I know 24 hours won't be nearly enough time but I think it will just convince me to book a return trip with my husband. I'm not a big shopper, but would be interested in a museum, beautiful architecture, good food, nice cafes and people watching. I enjoy photography so would love to find great places to take pictures to capture my brief visit.
I've done some quick searches, but haven't had time to do much research. I leave in 2 weeks for this unexpected trip so don't have much time to plan. Any advice would be appreciated.
