This studio apartment was a good value. I was alone and there was plenty of space. I think you could be comfortable with 2 people. I also wasn’t in the room much b/c Madrid has so much to explore!
Emilio was very responsive and thoughtful with all the items provided- maps, a Madrid guide, extra power strips, USB charger, dish soap, laundry detergent, fabric softener, coffee, tea, seasonings, etc. I felt at home. He also provided extra towels, pillows and blankets.
The apartment was not as clean as I’d have liked when I arrived, but I always wipe down my hotel rooms, AirBnB rooms anyway. I notified Emilio that the kitchenette and bathroom needed some attention; he responded right away, but the cleaner didn’t arrive until a couple days later. She did get everything sparkling. The beds are two twins pushed together. Pick one.
I would not recommend this place if you are sensitive to noise. I was barely there but you can hear the neighbors talk, sneeze, cough, etc. It didn’t bother me.
