Stayed for slightly over a month at The apartment along Calle Delicias. Juan was very helpful and warm. He's always available and constantly checked if I needed help. I was very pleased with the apartment and it was a short walk to Atocha station. Surrounding the apartment were several supermarkets which was extremely convenient. In addition, Sofia museum is just few minutes walk away. I would definitely recommend anyone who would like to find a place in madrid to stay in Juan's apartment.
