Let me start by saying, Sophie is an amazing host! She laid out the highlights of the town for us and which we couldn't miss. She called the taxi company to make sure we had a cab to take us to the airport early on our last day (and she was up and watching for the taxi to make sure it arrived at the place and on time).
The place is very clean, has a bedroom and a loft, so could be great for 2 couples. In terms of location, it's very close to a great restaurant, Le Pim'pi, less than 5 mins from Grande Plage and about 10 minutes to Cote des Basques.
One thing to keep in mind is the ~$40+ for sheets/towels rental. This is a 1-time fee that applies to the length of your stay (i.e. 5 days = $8/day).
This was a great stay for my wife and myself and definitely recommend it!
