Great little studio in Le Marais, 2 minutes from a metro station, with loads of restaurants within a few minutes walk away and 30 minute walk to Notre Dame. 4 flights of stairs up to the flat but to be honest it's really not that bad.
Kitchen well equipped with everything you could need, a boulangerie across the road for breakfast, all perfect!
The flat feels homely because of all the personal touches (records, CDs, books, ornaments, etc). All in all we loved the little flat, it was warm and cosy and in a great location.
Marc wasn't around (but he was very good and responding to emails etc) and his brother let us in and was very polite and helpful. Only downside was that we couldn't get into the flat until 7.45pm because the cleaning started late, but in the end it was fine as we dropped our bags off at 4 and then explored the city.
Great long-weekend experience.
