Irene has been a great host, she was flexible with the check-in and check-out time which is always appreciable. The flat has just been renovated with a very nice touch. The decoration is pretty nice and there is everything you need (Good Internet connection, kitchen hardware, coffee machine...).
The flat is centrally located in Madrid which makes it quite easy to go around the city.
Only one point to take into consideration, there can be some noise from the neighboors during the night.
But overall this flat is recomendable
