Awesome hosts (both Viviana and her husband who I got to briefly meet) and very clean place. They are very accommodating and I can honestly say as a result of this makes your experience that much better (was my first time in Madrid while my gf had lived here couple years ago). You also really can’t beat the great location as you’re literally close to every attraction but overall Madrid which lets you walk everywhere within 15 mins max or still metro to places if you’d like. That being said, you still have your peace and quiet during the night and even mid-afternoon breaks (aka sleeps) even though you’re quite central. Overall, if you get the chance to book with them, do it!
