If you're looking to be in the epicenter of Madrid, you can't get any closer than this beautiful flat with it's Juliette balcony looking into Plaza Major. It has been recently remodeled and has all the comforts you could hope for. Beautiful, modern and comfortable. Baths with heated towel racks, great showers, comfortable beds...the list goes on.
I can't recommend Mario Y Noelia's apartment enough.
