The location is awesome, it’s very close to metro and the Louvre and in the middle of a lot of asian restaurants if you like asian food. The convenience of close access to public transit really made our stay enjoyable.
The space is quite small as mentioned in other reviews, it’s between a studio and a micro-studio (for the US), but it is clean. I would not recommend staying with more than 2 people.
Additionally, there can be a bit of street noise at night so if you are a light sleeper, you might want to pack some ear plugs.
All in all I think this is a great deal if you’re okay with the noise and size.
