Communication with Dominique was excellent prior to our arrival. He responded promptly to our questions and Catherine (co-owner of the apartment) was very friendly and helpful on our arrival. She advised us about the location of a nearby supermarket and restaurants to dine.
Apartment was very clean and spacious as advertised. Our travelling party consisted of two adults and two teenage kids and at no stage we felt crammed during our 5 night stay there.
Location of the apartment for sightseeing is excellent with the apartment being close to quite a few of the Paris attractions (Louvre, Les Halles, Pompidou Centre, River Seine, Notre Dame), restaurants literally at the door step (Montorgeuil St is just 5 minutes away by walking) and Les Halles tube station (Line 4) about 3 minutes away by walking.
The Forum des Halles shopping centre is about 2 minutes walk away while other shops are also less than 10 minutes away.
Our kids loved the fact that we could walk to most places whether it was for eating, shopping or sightseeing. They really enjoyed the experience of walking in the surrounding pedestrian streets (only service vehicles and taxis are allowed in these streets).
Apartment is located in a busy restaurant area. This means that there can be some patron noise (no music was heard during our stay) in the open plan area, where the sofa bed is located assuming that more than two people are staying at the apartment (patron noise did not bother my partner and my older child as they slept without any problems for 5 nights). The bedroom is quiet as it is facing away from the street and there is also a door between the open plan and the entrance hallway which cuts out the noise from restaurants patrons and this meant that both me and our younger kid managed to get some good sleep.
Toilet is separate from the bathroom (which can be handy at times) and there was always hot water for all 4 of us to shower.
In all, our stay at the apartment was quite enjoyable and we will not hesitate to stay at the apartment should we visit Paris again.
