We were only in Madrid for a few days so we chose a simple room. It was very well located (big plus!) and just as described and shown in the posting. We had to wait a while to get in because they were out for lunch, which to us seemed a little inhospitable of them, but those are the rules!
The room was fine. Big bed. The bathroom looked a little too much like a prison to me. We had to bring our own toilet paper to the bathroom with us...the shower head did not work at all...no bath mat...
It definitely felt more like a hostel than it did an Airbnb. But if you're only staying for a couple days, you can tough it out!
Charlie was very nice.
