This is a top-notch airbnb. The location of the apartment is amazing: around the corner from Chueca Plaza and a metro stop. The apartment itself is supremely comfortable with excellent wifi and a/c for when you need it. The kitchen (though I didn't cook) is modern, state of the art, and equipped to cook, if you need it. The bed is super comfortable, and bedroom has black-out curtains. (Maybe the living room also has, but I didn't notice.)
There is a washer, and host provided laundry soap and softner, very kind in my experience. Also provided shampoo and soap for shower, also a kindness!
The terrace makes the visit extra special! Sun doesn't shine on that side of the building, so even on a hot day, you have a shady spot to sit, and in the late afternoon and evening to enjoy reading, talking, snacking, etc. There are comfortable lounge chairs and even a little table with two other chairs for your meal out there.
All-in-all, it doesn't get better than this for a travel experience.
