Antonella 's home is really nice and neat opera Metro station (Line 7 and 8)and Pyramides Metro Station (Line 14),and it has elevator to the 5th floor,so it's no problem if you have large luggage.spending a really good time with Antonella and her family members ^_^Paris is exactly very large,If you want to see all the tourists attractions,may be need 3 days.
Antonella的房子在市中心 ，走路去香街和卢浮宫，还有去CDG的 RER B线近郊铁路，都不远，巴黎最近雾霾比较严重，凡尔赛离市区1个小时RER，但是5点就关门了，建议早上一大早去凡尔赛，因为卢浮宫有可能你会想多逛一会，奥塞这次没来得及去，所以总的来说3天才够吧，因为景点有几个都是宫殿博物馆，时间长，从她家打车去戴高乐57欧元
