It is located just a few minutes away from the Chatelet station so it's very convenient to get to most scenic spots.
The room was clean when we checked in, but there was no replenishment of shampoo and shower gel (those provided on the first day was kind of one-off usage). It was lucky that we had brought our own shampoo and shower gel as fall back.
The most weird thing was that we were requested to leave the door key when we left the hotel, allegedly for "cleaning" and "security" purposes. However, when we went back to the hotel, we only needed to tell our room number at the reception to get back our door key without any identity / security check. (Those receptionists kept changing and there was no way he/she could recognise our face.). In short, our room virtually had no security because everyone could ask for the key and enter our room. This should be improved.
Apart from security issue, it is a good hotel.
