Fantastic stay! Carlos is a great host and amazing person. He made me feel so welcomed and at home from the very start. He's very nice and friendly and so helpful! I really felt great staying there. It's a very nice flat. The room is small but nice and clean with a comfortable single bed. Very nice kitchen and living room available to use. I had all I needed there. Tha location is brilliant with shops, bars and restaurants in the street and in walking distance to all tourist attractions. I will definitely book with Carlos if I'm in Madrid again. I absolutely recommend!
