I stayed at Consuelo's place for 2.5 weeks, so got the chance to make myself right at home! The location was perfect for me, very central and walkable to everywhere I wanted to go, though nicely set apart from the major touristy streets around Sol (less than 10 mins away, but still - this made a nice difference.)
The flat is lovely, very cute with lots of character, and had everything I needed. The roof terrace is a real treat on a sunny day, with fab views over the Madrid rooftops....the perfect spot for a drink and a bit of down time with a book!
Consuelo and her brother Manuel were incredibly welcoming and very patient with me as I tried to practice my basic Spanish skills!
Definitely a spot I would recommend to single travellers wanting a good base to explore this amazing city.
