We had a fabulous stay in Danielle's apartment. It is perfectly located on the edge of Montmartre with Gare du Nord just 3 stops away on the metro. Numerous local shops selling fresh fruit and vegetables as well as several artisan boulangeries and fromageries are a stones throw away and the area is well served with restaurants and bars - we enjoyed a great meal at La Renaissance (featured in Inglorious Basterds) such friendly and accommodating staff.
The apartment itself is lovely - with good beds (I slept on the sofa bed which is marvellously comfy), and everything else you could need, Danielle even has a stock of guide books and maps to help plan your Paris visit.
And lastly, but not least, Danielle herself was lovely, helpful and accommodating. Highly recommended.
