I was disappointed with the hotel. I book the room online probably 1 month at least before I leave for Paris and I did receive a confirmation from hotel.com. However,they changed my reservation to another location in Bercy without my agreement. They didn't inform me in advance and just told me this is their technical problem when I arrived the hotel. Finally,I have no choice but to accept their changing to Bercy or Opera.
The thing is this is my fifth time to live in Adagio Vincennes actually. I can't believe they treat the customer who came back here always. I scored them very good points previous 4 times because they are deserved. I don't know how to score and I don't think they are deserved good score for this case.
I'm thinking that I'll book this hotel again or not for my next trip because I'm afraid same situation happened again.
My personal opinion
To people who will live in this hotel, remember to make a confirmation again with hotel before you get off or you will live in a different place where you are unexpected. It seems that doesn't mean confirm even you did receive a confirmation from hotel.com
To people who would like to choose Adagio Bercy , I personally won't recommend this one because the quality and environment is not as good as Vincennes.
