The hosts were super supportive. Patricia's husband Javier drove us from and to airport (separate change), so we did not have to order taxi. The hosts allowed us to check in earlier (our plane was earlier in the day) for a little extra money. We communicated via Airbnb, and Patricia's responses and advices were timely and well appreciated. Patricia had also offered contact via WhatsApp, which we did not use. Apartment was clean and had everything we needed, including washing machine (drying on clothes rack outside the kitchen window). Kitchen is small, but has all necessities. Apartment is truly in center of everything - we did not walk more than 20 minutes to anything (most times, about 15 min). We did not use metro. Street is cleaned and washed every morning. 2 Small supermarkets on either side of the block - we preferred DIA. Bigger supermarket (and department store) - corte de Ingles - is down near the Puerta del Sol. Apartment has several solid core doors, to protect from outside noise. There is a nightclub on the street, could get a little noisy sometimes. All in all, pleasant experience.
