The summary is be CAREFUL. If location is the only parameter for you, this is your place. But be prepared to have problems in sleeping due to building noise. I am NOT talking about the noise from the street. There is the condominium door that is opened with a switch by the tens of users of the building. That makes noise. The opening of the door makes noise. Closing of the door makes noise. You will hear that A LOT in the night because the place shares a wall with the hallway and there is no acoustic insulation. The door does not insulate from noise either and you will hear people talking in the hallway.
In addition to the noise the place is very COLD: the living room does not have a heater and turning on the heaters from the other room does not help. The place has a small window in the small bathroom, the door, and the external large door that you will see in the AD. That makes the circulation difficult. Plan to open the windows often. The positive thing is a large refrigerator and the central location near the Abajadores metro stop (15 min). Not ideal for long stays because the lack of sleep you will get.
