This was my first time staying in a shared apartment (shared room), and the 4 Bears team made it a great experience! They shared timely information from the moment I made the reservation, and the check-in process flowed smoothly. The place was really clean and overall quiet at night. The bunk bed was also extremely clean and comfy; I appreciated that it had a curtain to have some sense of "privacy". Each bed had a USB port and larger socket for charging as well as an individual light. I only stayed one night, but would definitely return when visiting Madrid again.
