It was an absolutely wonderful experience staying at Almudena's beautifully appointed apartment. Though small in size, it was not a deterrent for us. Everything was in place and even the smallest requirements such as a needle and thread or a spare adapter were there. Guidebooks to all the appliances were stacked neatly in a drawer so that you had no chance to be stumped by the prospect of running something you hadn't encountered before. And best of all was Almudena herself, always a prompt message away. Entering or leaving the apartment and the building were pretty easy, with the neighbourhood being safe enough for late night strolls. It's just a 10-15 minute walk away from Atocha station, and the three great museums of Reina Sofia, Prado and Thyssen lie within a 20 minute walk. If you can foot it for 25 minutes, you're at Puerta Del Sol. A great, great location. For me, it's definitely not 'Adios' but 'Hasta Luego'.
