Anna's place is just as you see in the pictures - it is a compact space, but just enough for a BnB for one person. The bed is surprisingly comfortable for being a fold-out. Both the kitchen and bathroom are your typical Parisian super-efficient spaces, I probably would not advise cooking anything more complicated than pasta (although who goes to Paris to cook?)
The area is very lively and full of great places to eat, great to experience the 'real' Paris, rather than the tourist-packed areas in the centre. Three of Paris's best bakeries (Sain, Mamiche and Du Pain et des Idées) are within 10min walk of the flat for all your breakfast croissant needs in the morning! It feels very safe, as you need to get past a couple of gates before you get to the flat door. It is also a very quite flat, as it is away from the main Street.
All in all it was a great place to stay and would happily stay again! Anna was extremely good at communicating and would respond to any questions or messages within minutes. Merci pour tout Anna :)
