The flat is ideally located (city centre) and yet really calm. Everything was perfectly clean and the bed so comfy! MADFlats have been available each time we have been needing them (even on a Sunday!), plus they have offered for us to leave our luggage in their office after check-out (free of charge!) so that we could enjoy our last day in Madrid. We can only highly recommend their service and won't hesitate to rent this flat again (or any other of their flats) next time we come and spend a few days in Madrid!
