If you like the pleasant Tianmu neighborhood (bit far from center), it is a very convenient location with an excellent supermarket a couple of minutes away, a good yoghurt place, two health food stores, many restaurants. The Mitsukoshi department store is well within walking distance, and there are several buses.
The apartment is spacious though not luxurious. The master bedroom is the least quiet because of the bathroom window through which one sometimes hears talking and coughing from the building next door. It is quiet in the other two bedrooms.
Samuel is very pleasant and accommodating. And he speaks French!
