Antonio is a very helpful and gracious host. He does his best to communicate with you via a translator app if you don't know spanish well (such as in my case). He provides you with a map and a list of attractions and restaurants to visit. He and his wife are available to help with any questions you may have throughout your stay.
His apartment is decorated SO cute. It's exactly what is in the pictures. It's situated in a very popular spot with bars, tapas, and shopping. It's a five minute walk to the Plaza and the Market.
I could not have asked for a better location, apartment, or host! When I visit Madrid again, I will be staying at Antonio's Airbnb without hesitation.
