The prime location and ease of check-in for Paula's apartment make it a great option for travelers in town for just a couple of days, especially. I stayed overnight during a long layover from Morocco to the U.S. It was easy to get to the apartment from the airport via the yellow bus and to walk about 15 minutes (when you have luggage) from the Atocha station. If staying in the apartment during the winter or cooler months, be sure to find out how to operate the heater ahead of time. You'll need it if you like a toasty apartment like I do. :)
