Lovely, clean, modern apartment. Perfect for us as a couple with 2 teenage kids. Plenty of space and beds so the kids could have their own rooms. Location is ideal for short walks to various tourist hot spots, and for exploring the characterful narrow streets. Btw: narrow streets means no cars means no traffic noise - an added bonus we hadn’t thought about. This does however mean when you first arrive, don’t be surprised when the taxi drops you a street or two away. It’s only a short walk, but might seem confusing at first.
The cathedral and the Alcazar are close by, and worth getting a guided tour, and the flamenco museum is 2 minutes walk away - worth booking the evening flamenco performance.
Other recommended things to do with teenagers: a night time walk along the Metropol Parasol, and a guided sunset bike tour (See by Bike).
