The unit went above and beyond our expectations for our short stay in Madrid. Truly a rare find, especially for the price and location. It's about 2 blocks from a metro station and located in a lively but quiet neighborhood. It has everything you could need and more; There is even AC in each sleeping area! It also has a lot of charm when it comes to how it is decorated and designed on the inside.
Jose Antonio was also very timely in responding to all communication, including when we blew a fuse in the evening and when we needed to drop off our bags ahead of the check-in time.
When we come back to Madrid we will definitely lookup Jose's space again.
