The hostel has only online check in, follow the instructions and got it done just few minutes. I did before arrive to Córdoba through email link which had no issues. But other reviews showed some cellphone signal wasn’t good at site, plus there were no one at front door might have check problems. If plan to arrive late, get it done before arrival. when booking time comes, the hostel app shows numbers and room ( both outdoor and room are using the same digit number) app then provides WiFi information. The hostel very close to palace of viana and local bars around. It is very convenient and chill place to stay!
