We need to stay by emergency one night in Madrid, so we searched for every place near a train station. Luckily, Cristian place was available and he responded relatevily fast, so we reserved his place. It was walkable to the Achota train station, so we didn't need to spend money in transportation. It's just a tiny bedroom and a shared bathroom (I think that there is a kitchen available, but we didn't used it), but for the price and location, I really recommend it.
