Elena is revy friendly, is been quick to reply and gives excellent information. In short, she is a terrific host and makes you feel welcome in Madrid. Her apartment is tidy, clean, light and cosy - a very nice place to rest when in Madrid. It also has everything you need in it. And it is in a quiet neighborhood even if it's centrally located. She also provided maps and suggestions for sightseeing. I warmly recommend her and her apartment! I stayed there alone but would also recommend it for couples.
