Isaac's place is in a great location but we had a few issues during our stay. The beds were not large enough to comfortably sleep 2 people, so we had 2 of our 4 guests on the sofa bed. There was broken glass on the floor in one of the bedrooms, and there was a woman finishing up cleaning when we arrived. No paper towels or hand towels. The apartment is very small for 4 guests. I have stayed in much better AirBnBs in Madrid for less, so I will look elsewhere next time.
