The space is very beautiful and stylish. We loved the large open windows and open floor plan. The couch and seating were all quite comfortable and we had plenty of room to work, get ready, and relax during our stay. The kitchen is also suited with cups, wine glasses, coffee machine, toaster and anything you need.
The only downside is there is no real door to the bathroom. You can see someone in the shower from the main room. I stayed with a friend and not a significant other, so we put a sheet across the wall to provide privacy. We also could not use the projector, as there were no instructions and we may have needed additional cables, but overall it was not a problem and if we wanted to watch something we used our computer.
The metro is less than a minute walk with multiple lines, and a short walk from Grande Blvd and Hotel de Ville and central sites are easily walkable. Getting around was very easy. There is a supermarket quite close as well.
The building felt safe with the multiple codes to enter the building and the courtyard was quiet and peaceful at night. We had some issues with loud neighbors out in the street our first night, but the following nights there were no problems.
The location is convenient but not one of the most picturesque or polished areas, however once you are in the apartment it is very lovely and you will definitely not find this beautiful space for the price in Le Marais or St Germain des Pres.
I would highly recommend and stay here again in my next visit to Paris.
