Heide was excellent at answering questions and picking up the keys was easy although she was away on a long tour and we never met her..The apartment is a tiny, cosy, a mix of furnishing styles, in a back building, so away from the street and we didn't mind the daily trek up to the 4th floor. We had brought a fan with us as we were travelling in our own car after a holiday in the south, and we were glad of this even though we didn't have the hottest weather. It can be a bit airless.
The bed was super comfortable and we slept really well. It is quiet too.
The kitchen is a galley kitchen and is absolutely tiny - if you are bigger than a UK size 18, this place is not for you as access is by a narrow gap between the window and the breakfast bar! You might never make it around there!
We could not get the television to work at all but was not a huge issue as we had other things to do.
A few streest away is Simplon metro and this makes it easy to connect across Paris.
The immediate streets may be very Parisian, and are allegedly safe, but I would not have walked around there alone later at night and I was disappointed with the amount of litter on the streets.
We took full advantage of the food street market and tried to do the same with the shops but at this time of year, they are not all open.
For us there were issues over parking our car which seems so petty to relate but actually under our circumstances I had gone out of my way to sort this before we left the UK, given our holiday arrangements. There is NO free parking anymore on the streets except for Sunday and garage parking in the street is around 20 euros a day at the time of writing. Taking with the locals we got all sorts of conflicting information about this too, but all specified having a permit. Most people will come by public transport so that won't be a problem. (We eventually moved the car to another district entirely, at the end of a line and this meant anxiety and checking it every day).
Overall, for our first Airbnb we were underwhelmed and that is nothing to do with our host.
