I can't recommend this airbnb enough, the location is really central in Madrid--almost everything I wanted to see was within a 20 minute walk or I could easily take the public transit and be there in less than 20 minutes.
The Airbnb itself was great, it's a really cute studio space and I appreciated having the laundry in-unit. The terrace views are spectacular at sunset and you're right next to the terrace door so at night you can also look out the window and see the moon. The kitchen has a great mini-fridge for you to use while you're there and the bathroom shower has excellent water pressure/is really really nice.
When I visited, Andres was the person I primarily communicated with. He is really nice and super responsive. Since my flight arrival/departure were slightly inconvenient times for the typical Airbnb check in/checkout times he was able to help us accommodate those times as well as giving us some recommendations of places to see outside Madrid--like Toledo. I would definitely recommend staying here.
