The location was very centrally located close to the Louvre, Chatelet les Halles (RER to/from airport), 2 metro lines, a Monoprix and many, many restaurants -- the one across the street was excellent! The location was also located near a few peep shows and a mini red light district but felt extremely safe nonetheless.
The check-in process was very smooth and we were met at the apartment on time. I was also able to get a later checkout which was very much appreciated.
The apartment itself was well appointed with toilet paper, paper towel, salt, pepper, sugar and lots of pasta. I couldn't figure out how to turn on the TV as indicated on the information sheet just inside the door but we didn't really need it. We had planned on using the pull-out sofa but it was would have been too awkward to use as I'm not sure where we would have put the coffee table. Perhaps if there was a smaller table, it would have been easier to place aside. As well, the carpet should be smaller so that you can open the bedroom door without catching on it. As noted in a previous review, the lights in the bedroom stay on very dimly and wasn't quite sure how to turn them off. It was very convenient having the washer as well as the fridge. The shower was good but needed a good scrub. I don't think I truly figured out the key to the apartment but that was probably just me. Having said that, detailed instructions for the washer, TV, stove (if using), heating and key usage would have been welcomed.
All in all, it was a nice stay and I would stay there again.
