I can only speak to Alfonso's communication for this trip, since I had to cancel due to issues out of my control and did not end up staying in his studio. As my flight to Madrid was delayed several times, then ultimately canceled, Alfonso was (as he had been all along the way as I was planning my trip), very responsive to emails. He was extremely accommodating and understanding with several issues that came up. I was very much looking forward to revisiting Spain, and would be happy to stay at this accommodation in the future.
I highly recommend Alfonso for his courtesy, kindness, and honesty. I'm sure the accommodation is as clean and lovely as advertised.
