We stayed in Julian's apartment for 1 month in July/August. The apartment is well located about 5 minutes from the top of Montmartre area, although it is up steep stairs. Several Metro stops are nearby with Chateau Rouge just a couple minutes walk. The apartment is quite small as is common in this area and very full of the hosts own items. It is on the top floor of an older building with several good cafes/bars just outside the door. Several markets nearby make for easy shopping if you self cater. The apartment is pretty quiet at night but sometimes noisy during the day with construction during our stay. Overall a good experience but long stays may feel cramped.
