The place has a good location and it was very clean, unfortunately the check-in process is terrible, and you will end walking with your bags around the old city to retrieve the physical key if you are lucky to arrive during the week. The app does not work to open the multiple doors in the building and It will ask you for many documentation as proof of your identification. I felt very uncomfortable providing personal data of myself and everyone that came with me. People in the office are very helpful, they are aware of all the problems with the app, but OlaLiving still use that terrible app, as a result you have a terrible welcome to Barcelona.
