This is a great apartment, newly renovated so quite modern with good facilities. The size is quite large for Paris and the furnishings are comfortable. It's on the top (7th) floor of the apartment building but there is a very tiny lift which just fits 2 people, or one person and their luggage. Internet speed is very good, about 20Mb download and 1Mb upload.
The location is very convenient, just a 10 minute walk to several train stations. There are many shops close by including several small supermarkets, a few boulangeries, plus there is the Rue Mouffetard which has a great selection of shops for fresh produce. Chinatown is a 20 minute walk and you can get some excellent Chinese or Vietnamese food there. Also quite close is the Luxembourg Gardens where you can go for a nice walk or a run. It's 2km per lap so you can get a good workout.
I would definitely stay at Thierry's place again!
