Superb location, almost everything you need within 1-2 block around, including a 1-block walk to the Atocha train station. Host with excelent, attentive communications.
Comfortable beds and pillows with super clean linens and bedsheets. On the down side, if you are 6 ft tall, you'll have a hard time in the bathroom, which is on the small size...
Otherwise, will book it again
