A great little apartment around 10 - 15 mins walk from Place de Republic - comfortable and exactly as described in the listing.
For the 6 nights I was there, it served as a perfect base to explore Paris - and after a busy day had everything I needed to escape the business of the city.
There is a wonderful boulangerie and a cafe at the end of the road. There are also quite a few restaurants in the surrounding streets which seemed very popular with the locals.
We counted 4 or so supermarkets in 5 - 10 minutes walk and so buying supplies was very easy.
We did not see much of Sonia, but she helpfully provided us with her card and was very responsive and helpful when we did communicate.
I would very much recommend this little apartment.
