Pascal's apartment is extremely well located for discovering Paris. We used the local subways, Uber, and the public bike hire effectively. We spent 3 nights with 6 people which was a good amount in the space. The view from the roof is brilliant and perfect for pre-dinner aperitifs.
The rooms were good and beds were comfortable. Missing a few things that could have made the stay slightly more comfortable but in the end we didn't spend all that much time there - you're not in Paris to stay at home!!!
