Asha and Vincent provide a very clean, cozy, and comfortable flat in the 19th arrondissement, which, while it looks outlying, is a convenient location because of Paris' excellent public transit system. We had no problem getting everywhere we wanted on the Metro lines (though at certain times of day Metro cars can be very crowded).
Though in a very busy, urban area, the flat was very quiet. It mainly consists of a well-equipped kitchen (which we took advantage of for many breakfasts and a few dinners during our 10-night stay), a comfortable living room with a large-screen TV, and a bedroom with a very comfortable, roomy bed. A newly-tiled step-in shower and a small sink are in a room off of the bedroom, and the toilet is in a separate water-closet between the kitchen and the living room. The washing machine (in the room with the shower and sink) was a definite plus for our ten-night stay, and clothes hung on the provided drying racks dried surprisingly quickly. As with many older Paris buildings, there is no air conditioning (there are fans in the living room and bedroom) and no elevator in this building, but the flat is on the first floor, so it is only a one flight walk-up.
Asha and Vincent are friendly, good hosts who communicate well and clearly and are very responsive to any questions or issues that may arise. Do take advantage of their suggestions for local restaurants, bars, and boulangeries -- you won't regret taking advantage of their insights into local color.
