We stayed in Jamie's place for 5 nights and loved it - if we come back to Biarritz then we'll definitely want to stay here again! The apartment is pretty much exactly as it looks in the Airbnb photos - really clean, light and tastefully decorated. We didn't use the kitchen much (other than to make coffee), but it has everything you'd need to cook meals etc. if you wanted to.
The location is perfect - a few minutes walk away from the beach and town center, but just far enough away that it feels calm and residential. There can be a bit of traffic noise at night, but closing the balcony doors shuts it out completely.
Jamie was really helpful and friendly - always quick to respond to our messages and gave us some good tips for places to eat when we arrived.
