Staying at Alexandre’s place made our combo work/pleasure trip as perfect as we could have imagined. The location is unbeatable - extremely easy access to all of center city and to public transportation to access farther reaches of Paris. It is important to realize that due to proximity to the center city, political demonstrations or large events may affect ease of access at times, however the immediate neighborhood around the apartment is quite nice and felt safe. There are markets, bakeries, cafes, restaurants, and national monuments all within a few minutes’ walk.
The host is incredibly responsive and was kindly flexible with some last minute plan adjustments I requested. When we noted some issues with TV/internet it was fixed very quickly. The apartment itself is absolutely gorgeous - high ceilings, fresh paint, wood floors, beautiful trim, and all necessary amenities for a short or long stay. The floors make a bit of noise when walking around just due to age of the building, but that would likely only affect light sleepers. We had a baby with us and rooms are insulated enough that I really did not notice night wakenings from the second bedroom. Overall the building is quiet and comfortable with good security for access to the courtyard/apartment.
I would absolutely try to stay here again next time I have an opportunity to come to Paris!
