Anna was very accommodating to me and my travel buddy, as we were a day late due to limited times of train travels from Lisbon, Portugal to Madrid, Spain. Her apartment was spacious, clean, comfortable and close to the main train station (Chamartin) and Atocha station heading to Sevilla. We needed two nights in Madrid, so for the second night she allowed us to stay with her in an extra room in her own personal apartment for 40 euros (not a bad deal). Both her apartments were close to the main plaza and a short walk from the market, bars and restaurants. I'd recommend staying with her.
