The apartment was really nice. It has everything you need :) (two toilets, one shower, one bathtub, well equipped kitchen, TV, Internet, etc.)
It is renovated and new. Quiet neighbourhood. The next metro station is about 15 minutes by walking (Valdeacederas or Ventilla) Plaza castilla also about 15 two 20 minutes away.
The city centre of Madrid is much further away. About 45 Minutes.
