We spent a month in Almudena's apartment and it became our home. It is central, cozy and a geniune apartment we would like for ourselves.
It can be a little cold in the winter months and as most old spanish buildning, the wiring is not perfect, so you will cut the power If you use both oven, two hubs and the TV at the same time (there is a button to get power back no problem).
But for anyone looking for a home while in Madrid you won't go wrong here.
