I stayed in Olga's beautiful apartment for the last 3 months or so. I am a student from USA and found Olga and the apartment to be a blessing! The place is located in an vibrant area - Opera. On the other side of the street were the amazing Opera House and luxurious Palacio Real. Metro, bus and taxi stands right outside - could not have asked for a better location! Olga was an excellent host. Attentive, caring, and understanding. I thank her so much for the wonderful experience I had and I hope to visit Madrid again!
