Antonio responded very quickly to messages leading up to our stay in Madrid. He waited for us when we arrived for our check-in, explained everything, gave us some tips a map of Madrid and even arranged the taxi that was going to pick us up for the airport a few days later. I found the location of the apartment great! We were able to walk everywhere from there, The Retiro Park is not far away and it felt safe. I would definitely stay here again when in Madrid!
