Nice attic apartment in a safe working neighborhood. Convenient walking access to the Madrid's major tourist sites. Speedy internet (use all upper case letters in the very long password), and a responsive host. We stayed early April when weather was mild. Inquire about cooling for Summer stays when Madrid gets hot. I had to keep some windows closed either due to street noise or uncommon cooking aromas from inside the building.
Best Americano coffee I had in a long time, was just a short walk on Atocha street at Granier bakery! Overall, it was a pleasant stay.
