Fernando's place is great. The location for us was perfect as our family lives in Aravaca, only 5 minutes walk from the house.
For those that would like to visit the centre of Madrid, bus is just outside the house and is really quick to Moncloa where there is plenty of metro options.
Also, if you are bit too lazy like me uber, bolt and cabify to centre of Madrid is around 15 euros a ride.
The house is great, more spacious than I thought it would be, also overall is quiete and comfortable, and the little patio upstairs is great for summer nights having a drink with friends and family.
