I stayed in Emma's studio for a week and had a great time.
Emma was very easy to communicate with and was the perfect host. I had a few small requests during my stay (use of an iron, a late check-out on my final day) and Emma was more than happy to accommodate me.
Although the studio is quite small, it's in a perfect location right in the heart of the Marais, and for the price it represents great value for money for Paris.
The studio also has a fridge, a small cooker, and wi-fi which was extremely handy too.
I'd have no absolutely no problem staying in Emma's studio again or recommending Emma as a host.
