Delightful duplex in a central location. Clean, comfortable, and aesthetically pleasing. The terraces were lovely for the occassional meal or gazing at the Giralda at night. The downstairs bedroom was quiet -- the upstairs had more street noise but that's part of being in the heart of things. We did have trouble accessing Netflix which we never managed to resolve, but only the kids were disappointed. We spent most of our time outside the apartment, after all.
Not an issue for us, but perhaps worth mentioning that the staircase to the second floor is a longer climb than average (lovely high ceilings in the duplex) and both of the terraces are accessed through the bedroom on the second floor (so prepare to carry up a tray of food to use the outdoor dining space).
Nacho kindly arranged a very early morning taxi pickup for us and ensured that things went smoothly from check-in to check-out. We would happily stay there again!
