Karen is warm and welcoming host. I enjoyed staying her apartment. Location is splendid. Just next to Reina sofia. There is a lots of restaurant choice in neighborhoods. You can walk to 3 or 4 different metro station. And atocha is 5 min walk as well.
Her bed was very comfy. There is a desk and chair so you can work from her home.
Mucho gracias Karen for the warm welcome.
