This suite is beautiful. We came in late February- I can imagine in the spring and summer it'll be even better as the balcony will be warmer. But it's luxurious. The balcony is HUGE, and the views from it fantastic- you can see the top three or so floors of the royal palace and see the adjacent park. You can also see the park even better from the master bedroom.
It's modern, and stylishly lit. We hosted a small dinner party in it, and it was wonderful.
Can't recommend highly enough. Next time I go to Madrid, this will be my spot.
