Great location, very convenient access to the Atocha train station. Note that this place is essentially a hostal - when we were entering, there were signs marking it as a hostal in the building. It does seem a bit more clean that a typical hostal (I do not typically stay at hostals). The towels smelled horrible, it was not the cleanest place but pretty clean, and the room a bit dusty. Throughout the night, we could hear noise from outside and nearby rooms or rooms above/below the unit - typical of city area. It was manageable for two people as a one night stay for quick access to the train station early in the morning. In reading reviews prior to booking, it seemed like previous guests all said the place was really clean but I did not think it was "super clean" - but it is accurate that the location and convenience are excellent. Next time, I would probably pay more to stay somewhere else in the area - it may be a decent place though if you are on a budget.
