Luisa's place is great! It is very clean, cozy and comfortable especially because we had our private bathroom and little terrace in our part. It was like a separate "hotel room" in her apartment. The neighbor is very calm and safe. There is super markets, shops, restaurants... Her place is 1min walk to the bus station and 10 min walk to the metro station that goes directly to Sol.   Regarding Luisa, she is better than you can imagine! She helped us a lot with tours planning and gave us many tips for Madrid. For the "Fiesta Nacional de España" we spend entire day with her at Alcalá de Henares and we had wonderful time together. All in all, I strongly recommend this place!
