My first comment is if you feel the need to vist here - DON'T !!
This IS NOT a hotel - in my opinion it is undesirable student digs.
The carpet was filthy, the sheets were clean but covered with a disgustingly shabby and diry bedcover.
The kitchenette area was clean but the hob markings had faded so badly couldnt see what was on or off - trial and error.
Towels were thin and sparse. There was a note in the bathroom saying to save the environment only put towels that require washing in the bath - we did - and thats where they remained until we moved them.
The toilet was missing the seat, which was on the floor at the side of the toilet, we asked the receptionist if this could be mended and were told not until Monday - we arrived on Thursday and were leaving on Monday - not much use.
We were however offered to change rooms, this was our second room - the first having no electricity was cleaner ( albeit it was dark) and as they were gradually getting worse, we decided to stay where we were - better the devil you know!
The grout in the tiles was disgusting and the floor tiles didnt quite meet the shower tray and I wouldnt want to guess what lurked there.
The ceiling above the shower had cracks and stains - looked like a leak from the above rooms shower.
The rooms were not cleaned, nor beds made and there was an extra charge for any cleaning with an outrageous charge should the kitchenette require cleaning.
The bins were not emptied and you were expected to empty them yourself at the end of your stay. This was a route march through the basement into a filthy yard area.
The swimming pool was why I chose the hotel. This was not available, it was out of order, just a foul smell eminating from where the pool was supposed to be - it certainly looked like it hadnt been in use for some time.
The general public areas were passable, the lift had holes in the wall and mirror tiles missing but did work. Photos on the wall showing the interior did not match the reality in any way shape or form.
On the plus side it is situated near to the Grand Arch and the shopping centre there is huge. There are good train / metro and bus links to central Paris.
The room was adequately heated and sound proofing was fair in the rooms.
I took my husband there for a romantic 4 night break in Paris - we will return to Paris, we WILL not go back to the Adagio.
