Nader's place is great.
The check in was easy and he was very available.
He took time to talk to us about Madrid and guide us to hotspots.
The place is modern and very comfortable.
Only issue is that the power will go out if you're running both A/C at the same, a common issue in Europe, so be sure to close the A/C when not in the apartment.
Would recommend this place without hesitation.
Thanks Nader!
