The Check-In has been a disaster. I don't know how they usually manage it but in our case they first wanted to have selfies from each of us plus a scan of our passports through a platform the created. After paying and giving them all the information they asked for they did not answer anymore and let us not know how to enter into the apartment.
When we arrived in Dublin there was still no answer from them and we did not know how to enter the apartment. So we had no place to go to while constantly trying to get in touch with them. The only option to communicate was the chat through Airbnb where they just not answered.
Thanks god Airbnb gave us a refund and we could book another hotel in the middle of the night.
The people answered 2 days later at the end of our planned stay that we could ask Airbnb for a refund and that they are sorry for the late response.
I was afraid of them having all our documents as it looked like a scam. I wouldn't recommend anyone to book it.
