We had the best time in Kathryn's apartment! It's located in the best neighbourhood of Madrid, full of authentic places, surrounded by amazing cafés and restaurants. At the same time it's perfectly located, just walking distance to the main sites of the city such as the Reina Sofia Museum, the Prado Museum and Puerta del Sol in the city center. The place is very cosy and pretty and is located in a very stylish building. Book with your eyes closed! ;-)
