I had a great stay! Location is excellent — in a cool neighbourhood and just steps away from the metro. The place was as described, clean and comfortable.
Jaime did my check-in and was very friendly and accommodating. He even allowed me to drop off my suitcase/check-in ahead of schedule, which gave me several extra hours to enjoy the city! Great communication from both Rubén and Jaime. Thanks for being excellent hosts. Hope to visit Madrid again soon.
