Cristina and Fabiola's place is right in the centre of Madrid, right off the Calle Gran Vía which means most of the main attractions are within walking distance, with many shops around and I highly recommend it for the location. The house is sparkling clean and very quiet for being so close to the main road. Unfortunately there's no aircon or fan which made it a little hot in the summer but it's still much cooler than outside since the window faces the inner courtyard. It's unfortunate you can't access the kitchen but the wifi worked well and bathroom was large and lovely. You do have to be very quiet and clean in the house especially if you're the type to stay up later at night since they seem to go to bed quite early but if it works for you, it's a really lovely place to stay.
