This place was perfect for my trip. You are in the middle of everything. You can get on the train in Sol in five minutes or get on any number of metro or bus lines in the same amount of time. You have a lot of the historical monuments and parks within short walks as well. The live orchestra plays outside of El Corte Ingles across the street in the evening so the place comes with free classical music. Even though it's in the middle of town on a busy street, when I had the curtains and window/deck door closed I was able to sleep in just fine. Giselle was a delight who not only met me at 1am as I arrived very late but also helped me with laundry when I arrived. The only mild negative about the place was that the internet wasn't very strong or consistent but that's kind of a Spanish thing. All in all I'd definitely recommend this place to anyone with a lot of energy who wants to do and see as much as possible when they're in Madrid.
