If you want a smooth check in, HIGHLY avoid. The apartment was great, good location and nice layout. The check in procedure was just so bad that I would never want to stay with Ola again. You spend so much time before to register on an app that takes all your personal information and records it together with copies of your ID documents. And then you get to your holiday destination and the app does not work and allow you to check in as intended. All that effort and time wasted for nothing. In the end we still needed to walk to the office and get a key. We were also kindly notified that the office will close at 20h00. After we were already trying to check in from 19h00. We had limited time in Barcalona and had to run after Ola just to get a key to get in.
