I'm a very lenient guest that usually lets things slide unless it's something of major concern. That is probably why I didn't make any calls to the front desk on this occasion but there were certainly issues that made me have my doubts. Like everyone else mentions the location is fantastic but in my opinion not because of the shopping, simply because you are about a block away from the metro station and can be anywhere in paris within minutes.
I've stayed in many 5 star establishments prior to this, even had our wedding reception at one, and this is definitely not one of them. This isn't by any means a reflection of the staff who were always curteous, this is just on the hotel itself. First of all we arrived at our room and there were wrappers and chestnuts from street vendors in a few drawers that were left behind from previous guests. Like other posters mention no tea kettle in room and I'm not sure if there was work being done at night but it was quite noisy. Very noisy, actually. Didn't have a go at the breakfast buffet because based on other reviews I figured why bother.
My absolute main gripe, however, is how can a "5 star" rated hotel have such horrific wifi service that one has to pay extra for? I literally could not get any work done. Tripadvisor should really update their info on this place to reflect that it is only free wifi in the lobby area, not rooms. It seems like those of us that do have subpar thoughts on this place all complain about similar things (internet, noise, housekeeping) but they just don't seem to get resolved so just be aware of this beforehand. You definitely won't have a bad experience at this place, but it won't be great either. Simply average.
