We had a wonderful stay here as a family, the location is fantastic with easy access to the Louvre and Tuileries gardens with plenty of boulangeries near by to choose from for breakfast. A well stocked G20 supermarket nearby to buy essentials for a long weekend. Jazz bars not far and restaurants in St Germain are very accessible which made evenings very fun from here. Will recommend the flat as a base for friends/family visiting.
Only thing to note was the lack of oven glove and tea towel which made the kitchen feel like it wasn't geared up for cooking a proper meal in, but not essential as so many restaurants within walking distance.
