My wife and I really enojoyed staying at Airnaldos apartment. Everything went smoothly from the day we booked our stay. Communication was perfect, with clear explanations befor check-in and check-out. In the aprtment you will have everything you need for your stay in Madrid.
The fact that the apartment is located right next to the main Atocha railway station really helped us getting around Madrid and going on our day trips. Also the bus line from and to the airport stops on only 3 points in the and one of them is Atocha station. In my opinion this is by far the best location to stay at for a torist in Madrid.
