Fabienne's apartment was a single room, with lounge and bedroom combined, and kitchen to one side. It was surprisingly large, perhaps 5 m x 5 m, with high ceilings, so it felt spacious.
The bed is a sofa-bed. It folded out very easily (with sheet already fitted), so we just had to put on the duvet and pillows each evening. It was really comfortable, as good as any regular bed.
The kitchen was modern and had lots of modern gadgets .
The bathroom was of course separate. It was very clean, as was the rest of the apartment.
Feedback for some apartments in Paris complained about a lack of hot water - we had lots. Similarly, some apartments are apparently cold; we were in Paris during a really cold spell (frost every night with a maximum of 3°C each day) and yet the heating kept us warm.
The apartment is just outside of the busy tourist areas, so the local restaurants and shops were real French local places.
There are four metros within 10 minutes walk. Hire Velib bikes are just 50 m.
