Our stay was a really great experience. The location was central to a lot of restaurants, great shops and neighborhoods we wanted to visit. It is a couple minutes walk from one of the best metro lines for getting around the city to key spots, and walking distance to Montmartre. The finishings in the apartment were very thoughtful, and no detail was spared. Also, the passage it is in is very unique to Paris, and makes the spot especially memorable.
**Note: It hovered around 90 degrees while we were there, so pretty much anywhere without AC will be warm, but because the window looks into a small courtyard (very typical for these apartments) so there isn't much of a breeze to help the fan that Alice provided. Outside of the short heatwave that comes to Paris every summer, this should not be an issue.
