The apartment is great. Great size and has everything you need. It was very clean. The hosts were very kind and helpful. But the best thing about it its the location! Its in the middle of Madrid. You have no need for public transport. Money you save. Walking 20 minutes to one side you're on Retiro Park, 15 minutes to the other you're on Palacio Real. All you need is organize what you see and when to save money on transportation. In 5 minutes you have the subway and a 24/7 big Carrefour(supermarket)! And a public car park 3 minutes away. I paid 24 euros for 4 days but prices vary. Truly recomend
