Calm, comfortable and clean flat in a multicultural and lively neighbourhood. Pretty close by walk to some of main city spots like Gran Via, La Latina and El Rastro among many others. I had no chance for meeting Matti because he was abroad ( in return we met Raul, a Matti's friend pretty kind and friendly as well) but even far away from us he was always taking care of us by airbnb chat or whatsapp.
100% recommended.
