We rented the apartment for the month of May, and our impressions are very similar to other guests who have left comments. In one word: excellent!
Although small, the apartment has all you need for compact urban living: a cosy cave, filled with books and music, a warm, friendly atmosphere and good, functioning facilities.
As others have mentioned, the location is great: Canal Saint Martin, Oberkampf, République. The neighborhood is laid-back and crossover, a good mix of people and street life. Excellent metro and bus connections with all points in Paris.
Bouzra was a perfect host, always ready to answer our queries via e-mail & sms.
We warmly recommend this apartment to anyone looking for a great stay in Paris.
