it is not an hotel there is no reception, just a few lockers for the suitcases.....
I paid the full pricer 6 weeks in advance, and got numerous mails demanding me to enter various information in a shabby page. Discovering in front of the building they would be no reception I emailed the company. In reply, I was demanded, more details of my credit card within 20 mn or my reservation would be canceled.
I took us 2 hours, and calls to the call center to get the codes, being then lucky to put our suitcases in the only locker left.
For the services and the surface (minimum) of the room, an expensive & unpleasant experience.
