Ariel is a great host, helpful and polite, makes me feel literally at home. Whenever we have questions Ariel is always available when we need him. He is also kind enough to helped us to make a table reservation at Sobrino de Botín. The apartment is great, clean and quiet located right in the heart of Madrid. Puerta del Sol about 5 minutes walk away. Major tourist attraction are within walking distance too. Highly reccomended.
