Me and my friend were staying at Iris's place from 17.07 - 24.07. I have to say our first day was dificult as we couldn't meet with Iris's boyfriend when we arrived and it took about 2 hours to meet with him. Besides we had some problems with the key that he gave us - it didn't work properly! Finally our problem was solved.
However in spite of that our staying was nice. The apartment has a great location and it takes just 20 minutes to get to the center of Madrid. Besides Iris's place is fully equipped with all necessary items and has a wonderful view to Atocha train station and surrounding neighbourhood!
