You cannot find a better location for a home base as you explore the city of Madrid - it's conveniently located in the heart of everything the city has to offer. Marcos was one of the most responsive and accommodating hosts I've ever encountered, and the communication was very smooth. The only problem we had was that of the air conditioning - it wasn't working as expected and we spent the first night being mildly uncomfortable in the heat. But as long as we communicated that with Marcos, he called in maintenance to fix it, and brought in two big fans to help us in the meantime. All in al, this is a great place we'd recommend for everyone who's visiting Madrid!
