You will find an apartment trés chic, good equipped and really quiet. The location at Belleville is really good. Only 10 minutes away you'll find a really nice park where you can rest or take a great walk. Also the metro station is only 3 minutes by walking away. From the main station you'll only need 15 minutes by metro. Around the apartment you will find a lot restaurants, bakeries, bars. We assume, we were in the middle of little china town somehow :)
The apartment was clean and equipped with everything you might need. The bed is not made for more than two/ three nights. The hosts are really anxious and care about problems if there were any. In general a good place to stay in Paris :)
