I've stayed in over 100 Airbnbs and this was really one of the best. It really is just 20m to the metro station. The neighborhood is wonderful with fun restaurants and local shops in every direction. The building is a beautiful combination of old and new, the apartment is in excellent condition, and it looks just like in the pictures. Delta responded almost immediately whenever I sent him a message. I have a friend who owns some Airbnb's in Madrid and I can always stay in them at a reduced rate, but I think I'm going to try to book here first in the future.
