This is the perfect apartment for two travelers in Paris. The location (center of Paris) and view -- looking out at St. Sulpice church and square from one of the four windows and a short walk to Luxemburg garden (nice, safe neighborhood) -- is superb.
The owners and managers of the rental are the kindest and most considerate people I have ever met. They have gone over the top in providing many amenities such as blow-dryer, iron, TV, radio, CD player, free international calls phone, coffee maker (Nespresso, easy and delicious coffee), etc. They also live downstairs so if you need some help with something they are right there and more than willing to be of assistance (Claude printed our boarding passes for our return flight saving us from airport check-in). Of note: They make it clear that they will not bother you during your stay unless you call on them first.
Other notes: The elevator is very welcome after a long day of walking and hiking up and down Metro stairs.
The combination washer/dryer is effective but just a few tips if you stay here: Don't use a lot of soap, wash on "mixed" and dry on "delicate" with the dryness setting set on the picture of the iron. Your clothes will be slightly damp (dry in about 20 minutes) but it only takes one and a half hours as opposed to the three and a half hours on the regular setting which causes impossible wrinkles on cotton clothes.
The only slightly negative thing I could say about the entire apartment and our stay is that the bed needs a new mattress (slightly deformed in the middle). However, despite the slight deformity it is still very comfortable and my wife and I slept very well on it.
I would heartily recommend this apartment to anyone considering a stay in Paris. My wife and I are already planning on coming back and staying in this apartment (if it is available). Book way ahead as this is, understandably, one of the most desirable apartments in Paris.
