My wife and I had a very enjoyable 5-night stay in Carole's studio apartment in St Antoine in early October 2015.
The location is perfect for exploring Paris. The metro station (choice of 2) is only a short walk, either turn left or right at the front door, and you can be anywhere in the centre of Paris in under 20 minutes.
Carole is right on hand, just across the courtyard, to greet you and to help with any issues. We had everything we needed for a perfect base from which to explore Paris.
Definitely recommend this apartment to fellow travellers wishing to visit Paris.
