Carlos was the best host we could have imagined. Throughout our stay, he constantly checked up on us to make sure that we were enjoying ourselves, and he treated us like family, even inviting us to go to one of the most popular clubs in Madrid with him. The apartment was stocked with everything we could have possibly needed: food in the kitchen, towels, toiletries, guidebooks, and an incredibly comfortable bed. It was also in a prime location—it seemed as though nothing was more than a 15 minute walk away, and it only took 5 minutes to get to many central sites including the royal palace, Puerta del Sol, Plaza Mayor, and Mercado San Miguel.
