Jacqueline's studio had everything we needed for the kind of low budget tourism I usually practice - a place to rest and to make my own food, just like any normal household. I really felt at home.
The house was exactly what we expected after reading the add. Great Wi-Fi connection and all the kitchen and bathroom appliances needed - all of which were in very good conditions.
The location of the house is fantastic. Pereire station (metro and rer) is really close to the house, there's a monoprix right around the corner and the neighborhood is very safe and calm.
Jacqueline was very helpful during our stay, letting us take her lift to get our luggage up and down, so that we didn't have to carry them all the way to the 7th floor by stairs - this is the only obvious downside of the house, you have to get up to the 7th floor, in an old flight of stairs, to get to the studio; in my case, that wasn't an issue, but it might be for people with mobility problems.
All in all, I believe that this house is without a doubt, a great place to choose if you ever go to Paris and will contribute a lot in making your trip so much better. I highly recommend it to anyone.
