The flat is well located and only 20 minutes by taxi from the main train station- Gare Du Nord. The area around is bustling and only a 20 to 30 minute walk from the Louvre. There is also a metro stop nearby.
Area around the flat has lots of options for restaurants and bars. Although none stood out as particularly exceptional.
The building itself is located in a quiet street which is mostly residential but also has some commercial. Worth bearing in mind that the flat is on the third floor with no lifts.
Check-in is very well coordinated, with access to the key made possible through a lock box outside the flat.
The flat itself is a decent size, well lit and generally quite clean. Though the bathroom is not great - very tight squeeze and the shower area is in need of a thorough cleaning.
My only other complaint is that the duvet was dirty and without a cover. We did feel the need for it during our stay, but hesitated to use it due to its condition.
Overall, I think the flat is practical and convenient but quite basic and I did not feel I got value for my money. This is a flat you would book knowing that you would want to spend as little time in as possible.
