I had to go to Paris for two days for business and I decided to stay one night at this hotel. I arrived at 11 and they told me that the room was still busy, so I should come back around 15h. I came back around 16h and they offered me a coffe while my room was "getting ready". Finally, around 17h they told me that actually they didn't have any room available, although I had booked the room through their homepage and I had an email from them with the corresponding confirmation. Being already late, they offered to accomodate me in another hotel from the same group, which was a lower category one and where I got the worst room I ever had in a hotel. Being so late I didn't have much choice, but the lady from Hotel O told me that as a compensation I could get a drink at their bar. They have good reviews, because it's new, but negligence like this will destroy their reputation quite fast if they don't improve. To top the list of bad experiences one of the employees called Etienne was arguing with another one called Alex in front of 4 passengers. The one called Alex tried to keep face, but it was an uncomfortable situation that they should also avoid. Last comment I will add is that while having a coffee waiting for the room one of the managers passed by and asked "Is everything ok"? I answered "not really" and he just kept walking...why to ask, I wonder. You have only one chance to give a first impression, never forget that.
