The house is clean, has the ideal size for fairly small groups of friends looking for a place to stay for one night at the beach.
Towels provided, good oven, washing machine and tumble dryer available are really convenient
I would insist on the number of nights for the following reasons:
The neighbor hood doesn't offer anything worth going out when the sun has set. Therefore, it would have been great to have a more equipped place regarding cutlery, glasses etc.. This is clearly dedicated to be rented on Airbnb and furnished accordingly.
As stated in the other comments, it is quite loud since it's located right next to the subway, especially when not owning a car. Plus, the photo of the terrace (without any equipment) has been taken with the perfect angle/luminosity to hide its view: straight on the tracks.
On a side note, the water coming out of the kitchen was brown-ish. Having cooked with it but unnoticed at the time, we weren't happy when we figured this out in the morning.
To sum up: Book one night, bring your own food and drinks , enjoy the beach, it's the only thing to do within walking distance.
