We got back from a wonderful stay at Olivier’s apartment in Paris (stayed 6 nights from 11/22 to 11/28). We are a family of four, with kids aged 9 and 5. Despite going with little kids in the cold weather we had a fantastic trip. For those traveling with kids our age, we took a stroller for the 5-year old which was helpful as it allowed us to walk everywhere without dealing with a tired cranky child.
It truly is a great apartment in a central location in the heart of Paris. As other reviewers have stated, a majority of the tourist attractions are close by within walking distance. We walked to the Norte Dame, Saint Chapelle, Seine Cruise, Pantheon, Louvre, and Marais district. We also availed of the metro (station right across the street) to visit places like Sacre Coeur, Eiffel Tower, and Champs Elysee, as well as the train ride back from Disneyland. That said, we also freely used Uber as needed. The Les Halles neighborhood is vibrant with lots of shopping, restaurants and bars in the vicinity. If you like overly chic neighborhoods, stay in the Champs Elysee or St Germain areas. I liken this neighborhood more to staying in the Times Square area when visiting New York. On weekends there was noise on the streets until 4-5 AM from young partygoers. But it was quiet on weeknights. We felt safe at all times.
Olivier was a helpful host always ready to provide useful tips and local guidance. Before we arrived in Paris he recommended day trips that we could (and should) take with the kids. While we were in Paris he warned us not to go to the Concorde / Champs Elysee on Saturday as there were demonstrations taking place in those areas. He is very quick to respond to texts / emails.
Lastly, if you are going with kids or as a group of youngsters, know that this is a classic apartment building with neighbors that are quite sensitive to any noise. We were clearly warned of this by Olivier upon our arrival and therefore kept the kids as quiet as possible (which was definitely challenging with kids our age - they were jet lagged and on a holiday too). We had someone loudly bang on the main door one of the mornings while we all were asleep. Never found out if it was one of the neighbors but that was a touch disconcerting. Other than that incident we encountered no other issues.
In summary, this is a fantastic place to make your home while you’re visiting Paris. Highly recommended!
