The apartment is probably the cleanest vacation rental we have ever stayed at. Absolutely spotless! In fact, considering there are no soft furnishings, I would recommend this rental for anyone who suffers from asthma or similar allergies. Dust won't be a problem here.
We were impressed by high-quality appliances, fixtures, and fittings. The bed was very comfortable, as were the beddings. In the bedroom, there was also a spacious wardrobe with plenty of clothes hangers - not a given.
The location is excellent. There are 3 metro stops relatively near, so you are well connected - very easy to get to e.g. CDG using metro and RER B. There are small grocery shops, bakeries, and plenty of restaurants nearby, as well as Le Bon Marché, with its food court, La Grande Epicerie de Paris, just a block away. The street is relatively quiet, although you should make sure that you have earplugs if you like to sleep late - the bin men arrive around 7 am.
Both the owner, Simon, and Mme Catherine, who met us at the apartment and keeps it so clean, were quick to respond and very helpful, doing everything they could when there were issues with the building's communal heating/hot water system.
We hope to be back soon, if Simon will have us :)
