This was a great place to stay! I was here for about 3 weeks and it was fantastic. Raul is super responsive and very willing to help with any problem you may have, as well as help you around the city. The location is pretty unbeatable right next to the palace and a 5 minute walk from Mayor and 10 minutes to Sol. My only warning for long term stays is that there is not a ton of natural light since it is a ground floor apartment, so just be sure to spend some time in the Madrid sun each day!
