The best about the apartment is the location, some steps away of the Metro line 8 and the Tram T3. It's very easy to get into the city and from the Airport to the apartment. The apartment is not big, but you spend anyhow your time in Paris or around. Please watch to buy the correct tickets when you travel to Versailles or back to the Airport, otherwise you have to pay a penalty. It looks to me it's a business to catch tourists, who had not the correct one.
