I arrived with my family on a Friday at 4:00 for check in for a two bedroom large apartment. We were there for my daughters wedding. It was to be our home base where we were going to prepare for all of the events for the weekend. Earlier in the day we had recieved an email with checkin information and a code for that day. I used the code and it didn't work. We called the helpline listed in the email for Sonder. The operator gave us another code to get in. We opened the door to find that there were other people's things in there. The operator then told me that our reservations started on Saturday. I had email confirmations for Friday and had paid in full for Friday-Monday. She argued with me for quite some time. Said my number didn't show up as ever calling before or being associated with an account. I emailed her my confirmation and she proceeded to blame AirBnB for the double booking. We waitied on the phone in the hallway with all of our things for one hour and 24 minutes until she finally was able to get a code to let us in a room. A one bedroom, small room for my entire family and was told that the next day we could get into the room we paid for. There was pubic hairs in the bedding -it was obvious it hadn't been cleaned well. The next morning as we were preparing to leave to run errands for the grooms dinner and wedding I received emails and text saying that 1. I had to check out of this room by 11:00 and that I couldn't check into the room I had already paid for until 4PM. We had flowers, wedding decorations, food etc. We didn't dare leave for fear of our code not working when we returned and wouldn't be able to get our things. I spent about an hour Saturday morning calling, texting, emailing to make we would have a place for our things and a place to stay. Preferrably in the room we had PAID for. After much insisting we were finally allowed in our room. Once in the room there was an half eaten oreo cookie in the closet. The apartment itself is absolutely beautiful but the service was about as poor as it gets. It was such an unnecessary added stress to my daughters wedding weekend. Definately not a repeat customer.
