Just got back from a 4 night stay here and wish we could have stayed longer.
The room was large and clean, the location perfect - 3 minutes away from Jourdain Metro which gets you anywhere very easily. There's not masses to do in Jourdain itself although it does have lovely boulangeries, cheese shops and so on. But it's so close to all the main sites - never more than about 15 minutes on the Metro.
The place is run by such a lovely host who made us feel very welcome and looked after, and the best thing about it are the amazing breakfasts every day. Heaven. Loads of bread, jam, butter, pastries, cheese, ham, fruit and of course lovely fresh coffee. Yum. If the weather is nice, breakfast is served outside in the pretty courtyard.
It can be a tad noisy at night if your windows are open which we did due to the heat, but with them closed you can't hear anything. We will definitely be coming back.
