I stayed with my mother in this apartment in Paris. It's located in a great part of Paris surrounded by upmarket shops so we felt very safe. It is conveniently close to metro stations to easily reach all the tourist sights. There is a 'Monoprix' store on the way from the metro station to the apartment which is a supermarket where you can buy any food or other essential items.
As another guest said, the building does have a lift but there is one flight of stairs to reach it, which we knew before hand and were prepared to climb with our bags so that was okay.
The heating, wifi and shower worked great. We only ended up using the microwave, toaster, fridge and dishwasher in the kitchen which also worked well. The sofa bed was easy to assemble each evening and comfortable for myself while my mum slept on the main bed.
The whole apartment was clean and well thought out. Tiffany provided loads of helpful information as well as access to the landline phone to call her if we needed.
Thank you Tiffany for an easy and pleasant stay in Paris and wonderful first introduction to Airbnb!
