We had the best time and I definitely recommend Simon's flat.
This place has had mixed reviews. If, like me, you're booking this place because you want to holiday on a budget, then it's great. Don't book it and then expect the luxuries of a Hilton because that's not fair. For the money you pay, this place is excellent value - the location is great, on the street parallel is a bakery for your fresh croissants and baguettes, a little supermarket (8 a huit) and a couple of lovely little restaurants and a wine bar. Literally just around the corner is the tourist office and the bus stop for many destinations (we took a day trip to Bayonne for $2 return which is beautiful and worth a visit and we also took a bus up the coast to Cavalier beach for $2 return which was gorgeous and much quieter). The flat is about a five minute walk into the town centre and there is a market every morning until 2pm. The beach, from the flat, is no longer than five minutes away. Port Vieux is maybe ten minutes away by foot - and I'd definitely recommend the rooftop bar which is very very cool.
In all, the flat serves what you've paid. The sofa isn't the comfiest sofa you'll ever sit on, it's basic and small, sure, but for the money I paid, I wasn't expecting anything more than that. I had the best holiday and I hope to visit again.
