Yina is super super great, I regret that I only stay for two nights, I should stay longer because Yina is really really nice and friendly.
The house is warm and clean and comfortable, the location is good and convenient.
I can easily walk to some attractions, and it's near metro and bus stop, also it's not far away to the airport.
I will highly recommend eveyone who visits Madrid reserve Yina's house, and I will definitely reserve it when I visit Madrid the next time.
