Andrea's place was outstanding. In addition to a comfortable bed, great shower, and a useful kitchen, it was a very comfortable and beautiful space. There was lots of natural light, and really good lighting inside. The apartment also had great flow. It is easy to move around without anything getting in the way. It looks like a lot of thought went into this apartment.
There were also large sliding doors if you wanted to have a bit of privacy in one of the rooms.
As to the location of the apartment, it was about a one-minute walk at street level to the Metro and a short five minute walk to Gran Via. In addition, there were a lot of good restaurants in the area. Andrea also provided some great recommendations for restaurants.
