We stayed at the apartment from July 06 thru 12th, 2014 as a family group of 4. The location of the flat is good if you look for accommodation in the 15th arrondissement respectively near the Eiffel tower. You are very close to the metro station Motte Piquet Grenelle.
The apartment is fine if you can put up with things in need of repair and in general a low level of upkeep. The specification of two bathrooms is misleading. You have a half bath with a tub and another half with a shower cabin and sink. There is only one small WC for the entire flat.
