Elvira is a wonderful hostess and her apartment is sunny and spectacularly located, right behind one of my favorite architectural marvels Caixa Forum, within walking distance to the train station, the Prado Museum, the Reina Sofia Museum, and the Thyssen Bornemisza Museum. The narrow room is sparsely furnished with tons of fabulous books, a comfy and cozy bed, and a table. I loved the cleanliness. Elvira kept the apartment on the cool side to conserve energy, so you need to ask to get the temperature to your liking. Also, plan your shower to avoid being left with no hot water while still shampoo or conditioner in your hair. Finally, plan for your breakfasts elsewhere because there is none available at the apartment. Having said that, the location is unbeatable for museum lovers - and it takes days to really get a chance to see the amazing collections - and those who want to take day trips. Cheers
