“I am rating 1 star because 0 star is not an option.I am an Executive Assistant in a company with 500+ employees. I made a group booking in the "AC Hotel by Marriott Berlin Humboldthain Park" hotel for last night; there were 9 people from our company in the hotel.One of them (who of course happens to be our CEO...) had a disastrous experience there.When he arrived and asked for his room at 4 pm (usual check-in time is at 3 pm), they told him the room was not cleaned yet but that it'll be ready for when he would come back in the evening. After our Berlin team party, he came back around 2 am then they gave him the key to a room already occupied by someone! He had then to leave and go to another hotel because the hotel was fully booked.He saw this morning that they had sent him an email past 11 pm last night to tell him they made a technical error, and that he needed to go to Precise Tale hotel instead. An email? At 23.00? Who check their emails at that time?The rest of the group was ok even if they had single beds while I booked super large beds for everyone (and paid for that type of rooms too)...For a hotel that claims to be under the Marriott brand, this is a disgrace. This is a rip-off, and I would not recommend anyone to book a room there, especially during the summer holidays period.If Marriott/the hotel have any decency/honor, they will contact us to do something and offer to refund us the price of his night in the other hotel.In any case, this hotel is a hard pass for us.”

“Ele faz algumas coisas certas, no entanto, o quarto que tínhamos no que pode ter sido o dia mais quente do verão não tinha ar-condicionado (não está claro se deveria ser) e estava no lado mais ensolarado e barulhento do prédio. Não tínhamos escolha a não ser manter a janela aberta o mínimo permitido. Sem dormir. A localização é conveniente e as pessoas são simpáticas, mas não ficaríamos lá novamente, especialmente nos dias mais quentes.”
