I very much enjoyed my stay here and will book again my next visit to Madrid!
Augustin went out of his way to communicate with me about how to find him (I ended up not getting a SIM card that worked with my phone so was relying on wifi/WutsApp to communicate - I was also taking the Metro and walking A LOT!) and even though he was away when I checked in he had a very nice friend waiting for me to let me in. She gave me the keys and explained the basics of the apartment.
I felt at home, slept well in the bed and enjoyed the view of the room facing the street. I was able to get around to the museums, at times walked...only a 20 minutes away, and got lost then found my way due to the great location and had fun doing it!
Staying in November was casual as far as the apartment which was warm, had good heat and I like ventilation so the window was open a bit for a perfect combination.
Thank You Agustin!
