Marina and her mother welcomed me with great kindness.
Marina even went out into the streets looking for me when she thought I got lost.
Apartment description is accurate.
Strong wifi signal.
The bed was big and comfy and the bedding was luxurious.
The neighborhood is very upscale, expensive and conservative. Not as lively or trendy as other areas. More settled and quieter then other parts of Madrid.
Apartment is two blocks from the Metro.
If arriving by Metro you may want to travel light because there a quite a few stairs to ascend at the station.
