Mercedes and her husband were amazing start to finish. They even allowed my boyfriend and I to check in much earlier no problem at all. The apartment is in an amazing location with all you need within walking distance for the best tapas! Close to Playza Mayor and next to the metro for transit. We loved the area, it was so great you really don't need to leave! The apartment was spotless, and she was sweet enough to leave the fridge filled with juices snacks, coffee ect! To top it off she left me sunscreen because of the heat. The apartment has everything you need including an amazing hair dryer which was hard to come by as a girl traveling through Europe! They made sure to check in on us, and even called us a taxi to take us to the airport on check out. If your looking for a perfect location and place to stay in Madrid I recommend this apartment! Hope to be back!
