We had a lovely time in this apartment, it's in a great location not far from the pompediu centre and 10 min walk to Norte dam, 20 min walk to the louvre.
The apartment is all newly renovated and is perfect as a base with everything you need for a few days. It is compact, but that is no problem as you will be out exploring this exciting area of Paris. It is warm, and quiet (while we were there).
Louise is very helpful and flexible, and resolved an issue for us very quickly, and responded very promptly to emails.
Would definitely recommend.
