I spent my first night at Madrid in Ariel's house. First of all, this house is very close to the Plaza del sol, the hub of the Madrid. So, I could visit any attraction in Madrid by walking for short time because my room was at the center of Madrid. Second, all necessary stuffs for living (bathroom, kitchen, and wi-fi) are well prepared. Finally, Ariel is really kind to visitors like me, so he comforted me a lot (I was little bit nervous because it is my first trip abroad). I strongly recommend to enjoy one night in his house
