Very nice studio. Possibly a bit of more natural light would be nice but at the end if you are in Paris for tourism, you will only be there for breakfast and sleep.
The area was very convenient for us. 10 minutes to Gare Du Nord station. Walking distance to most touristic places (circa 1 hour).
We had an issue when we got there as we needed a cot and high chair and when we got there there was none. Baruck provide us with a cot and high chair pretty quick though and also gave us some delicious "treats" as an apology.
