During our Paris trip last year, we stayed at our timeshare outside the city near Disneyland Paris. It was roughly a 40 min train ride into Paris. I didn't mind the extra time needed to get to the city since mass transit was available in the evening. We didn't need a taxi at all.
I recommend arriving to Paris on Sunday or Monday to take advantage of the Paris Train metro pass, Navigo Decouverte. It's a smart card for a week/month that is valid on bus, metro, RER, Ile-de-France (Transilien) trains. The Navigo Decouverte pass price is available to visitors and valid only from Monday at 00:00 to Sunday 23:59:59. Additional details about this pass can be found
here.
Before we left Paris, we stopped by the infamous love locks on the Pont des Arts bridge. We attached our padlock to the bridge but unfortunately, the locks were removed last
June. I'm glad we didn't purchase a fancy padlock for it to be removed this year.
Compared to other cities in France, Paris seemed to be english-speaking friendly. I didn't have a problem getting around or ordering at restaurants. The one change I will make the next time we're here is planning a trip in May than in March since it was cold and rainy.
