The hotel is not great, but it is in a fantastic location for sightseeing, which is why I am giving it 4 stars, because the location is AMAZING. It's really a 2.5 star hotel at best.
The shower in the room is bizarre since you only have a third of a shower door to block water from splashing everywhere. The rooms are old, worn, and a little depressing if I am honest. Some people might view the age of everything as "charming" but I felt it was run down and needed some sprucing up.
The bed was okay, and there wasn't a lot of outside noise heard in the room which was nice. The guy at the front desk wasn't that friendly when I was leaving because I didn't physically stand there to check out and talk, and he made a passive aggressive comment about how people check out of hotels in the US versus France.
But, again, if you are in Paris to sightsee, there are restaurants and cafes all in close proximity, and there is shopping plus all types of touristy places to visit, all steps from your room. For the price and the location, it's worth it.
