Our first time using air bnb and we will certainly be using it more often. Had a wonderful 4 night stay at Ben's apartment. It is exactly as it is described and appears in the photos, so open, clean and light (and cosy and warm if you are there in Jan like us). Location is perfect, literally 1-2 minute walk to a supermarket, Notre Dame and all the shops/restaurants in the latin quarter. Less than 5 minute walk to the metro which goes directly to the airport (we had no need to use a taxi once during our stay, the metro in Paris is brilliant!). Also a very safe area.

If you compare the price for comfort/size/location of this apartment with any of the hotels available in the area, this is just by far the best value option! We would certainly recommend this apartment to friends and family and will return if we ever come back to Paris.

A couple of other suggestions for visitors (not related to the apartment so much) -

We didn't think to ask for recommendations from Ben for restaurants, but we did find two great restaurants less than 5 minute walk from the apartment (worth doing your research before dining out in the latin quarter, otherwise you will 100% end up in a pretty average tourist trap - like we did on night one)
Le Petit Chatelet & Le Tournebievre (our personal favourite)
Also if you are getting tired of cheese and ham baguettes for lunch, we would really highly recommend Verjus (close to the louvre/royal palace) - we went twice!

We also did a 3 hour private walking tour with 'Paris by Martin Private Tours' (ranked number 2 on Trip Advisor) which we would highly recommend (it avoids the major sites and focuses more on hidden sights in paris).
