Ich kann nicht einchecken oder sie werden einfach nicht eingeblendet! Außerdem ist es sehr nervig wenn man eine Buchung umbucht, diese kann man dann in der App nicht mehr sehen bzw. man hat keine Chance diese hinzuzufügen!!! Bzw den Check in durchzuführen. Macht bitte wieder den Web Checkin möglich !!! Bitte !!!! Wieso wurde dieser entfernt ??? ### 4/5 — Long registration *2026-05-28* I already paid and took care of booking . When checking in I had to manually input all of the information for my family (6 of us) into their downloadable app. All other hotel require the person paying to do it. Ridiculous truly! Then it asked my family members to enter their visa number. They don’t have visa numbers because they are visiting from America. I couldn’t submit their info until I came up with a visa number. Frustrating ### 1/5 — Buggy & stressful *2026-04-24, version 3.3.4* Refuses to accept valid email addresses, generally a stressful experience when trying to book into your accommodation. ### 2/5 — Horror Show *2026-04-16, version 3.3.4* Stayed at the Copenhagen hotel for 3 nights from Monday to Wednesday with my wife and 2 children 6 and 9. We arrived at 1am, Rooms are clean but we had to make beds ourselves. Staff were great, I had a hypo and one was a great help. 3rd night was a horror movie. People constantly running up and down the halls screaming, banging doors constantly. I can only assume they were a big group who knew each other and trying to wind each other up. This went on from 8pm to 3pm. Might have continued beyond then but we had a 6am flight to catch. This meant we had no sleep all night and unfortunately I wouldn’t reccomend staying in an A&O hostel to anyone. I know it’s a hostel and I can accept noise up until around 10/11pm or on weekends but this was a midweek on a Wednesday. Sure it’s great if you’re a student. ### 1/5 — Misery *2026-04-03, version 3.3.4* Clunky, weird UI, and a ridiculous check-in experience. Wrestle all your personal info into the app to check in, then wait for an eternity while staff members manually do everything you did on the app anyways. Ultimate example of just making everything worse by poorly implementing a digital solution and calling it modern. Just start over ### 1/5 — steals your money *2026-02-26, version 3.3.2* I booked a room via booking.com and got messages via that from a&o asking me to check-in via the a&o app, so I got the app, went through the check-in process which asked me to pay in full, was taken to a blank page with no confirmation after I paid, but the payment was pending on my credit card app. I explained this to the hotel reception staff who called head office or someone and since the app never put a payment confirmation on their system they took payment from my card via booking.com. So I was charged twice for the same room, and twice for late check out. The app just steals your money! I’m trying to get a refund (and having to get a&o support emails translated from German) ### 1/5 — aktuell nicht zu gebrauchen *2025-12-29* Leider arbeitet die App aktuell nicht gut. Beim Check-in werden Extras gebucht, die nicht löschbar sind und Extras angeboten, die es nicht in jedem Standort gibt - Problem: das Personal kann nicht helfen, da die dieses Extra gar nicht angezeigt bekommen, merkt man leider erst, wenn schon bezahlt ist. Die Preise für die Bar sind vor Ort leicht abweichend und der Türöffner scheint so oft nicht zu funktionieren, dass das Personal sofort die Keycard zückt, bevor man den Satz zu Ende gesprochen hat… ### 5/5 — Mn *2025-12-28, version 3.2.0* Erd ### 1/5 — Save Time for Everyone *2025-12-26, version 3.2.0* This Organisation needs to ask all guest to pre-check-in when bookings are made. It can save guests queuing up for 1 hour at Reception Only to be told they need to Check-In-Online ### 2/5 — Spam *2025-12-02, version 3.2.0* 36 Nachrichten innerhalb weniger Minuten.
