This is a great apartment, very well located, clean and overall we had a great stay. My only heads-ups would be:
- the fact it might be a bit noisy (mostly the weekend)
- the room under the roof was really really hot (because the temperatures in Paris were really high during our stay)
- the apartment would benefit to be better supplied: soap, dish washing product, a few basic products (salt, pepper, sugar, ...). When coming from abroad just for a few days, you don't want to have to worry about those.
