This place was one of my favorite places I have stayed at in Spain, the Airbnb was clean and in a very convenient and lively location. There is a large variety of stores and restaurants within a 1-minute walking radius.
It is located at the 4th floor (5th floor for us Americans) but we didn’t mind and quickly became used to it. For the sake of a good review I’ll say my biggest downside was a small problem we had in the initial check-in where the code wouldn’t work, but customer service was very quick to respond and fixed the situation within a 1-2 minutes. We were very impressed at their responsiveness. My girlfriend and I agreed it was our favorite apartment we have staying in Madrid. And because of this, I would 10 out of 10 come back!
