The hotel seems OK at first, but I had some bad experiences:
1. The hotel seems to be built above a busy subway/traintrack, and every few minutes you hear and feel a train passing by, which make sfalling a sleep just a bit harder.
2. The pillows are very flat and hard. I've had much better in other hotels
3. The amenities are very basic and cheap: not toothbrush, no raisor, only a bottl of 'one for all' gel in the shower and a very small piece of soap in at the sinc. To my surprise, there was a free small bottle of evian in the fridge.
4. Like in most hotels, there are traces of fungus in the corners of the shower. I think they can do a better job at trying to remove this with specialized products.
Some plusses:
Very friendly staff
Good WIFI
You can squeeze your own oranges to make juice at breakfast (in a machine)
Some glutenfree products, though I think they can do much better than the current offering.
The Hotel can be easily reached with public transport, though it is just outside of the 'centre of Paris' so a standard metro ticket will bring you as far as La Defense on line 1, at which point you need to decide to pay for one more trip on the RER train (1 stop) or walk the last km on foot (just cross the arch to the other side and you're almost there)
