Firstly, Sophie‘s place is probably one of the best locations you could live at. It‘s near both Saint Lazare and Opéra, right behind Lafayette and very close to numerous restaurant and supermarkets.
As for the studio, it really is small, I lived here for three weeks and had no problems but I would imagine for (more than) two people it could get difficult.
I had no problems with electronics such as Tv, wifi, fridge or Microwave.
Great was also how sound-proof the studio seemed to be. As soon as one closed the window, the outside world felt shut away.
I encountered but one small inconvenience: In the evenings, and on the weekends sometimes also during the day, there is a strong smell of Marijuana/ weed both outside and in the staircase. Though not a fan, I normally don‘t mind the smell but here it was a very intense scent. Of course this is not Sophie‘s fault but I thought I‘d mention it since for other people it might be important to know.
Nevertheless, I thoroughly enjoyed my stay here.
