We had an amazing time in Paris and the studio did exactly what we needed. We put wine and cheese in the fridge for when we wanted to relax and it was and easy walk to the tube.
The only disappointment was the fact we did not know there were very young and slightly children living in the house. As the floors and doors are very thin it was difficult to have a lie in or relax in the morning/early evening as we could hear a lot of shouting and banging.
Apart from that he studio was exactly like the photos and very clean and pretty.
They also took our bags on the last day as we went to the Louvre before the airport which was unbelievably helpful and kind.
All in all a great 4 nights and I would recommend. Only suggestion is adding in the fact young children live in the house.
