Julian's flat is a truly unusual, chic little place. It's on the fifth floor of, I think, a thirties block, very Alfred Hitchcock, friendly neighbours, a little light-pool courtyard in the centre. The flat itself is compact but beautifully done, in dark greens and teals, full of pictures and interesting oddments, exquisitely laid out. You're right in the centre of Montmartre, with the imposing Sacre Coeur looking straight down on you, surrounded by fabric shops and boutiques, very near Place des Abbesses which is packed with restaurants. Excellent public transport links. If you're getting the train in to Gare du Nord, you'll be there within 20 minutes of your arrival time.
