We have a spa now
At 300 steps from Le-zen - I counted them, I really did - we can make use of Pierre's wonderful indoor swimming pool + sauna + hammam. I tested all of the facilities and it feels like a fantastic treat. Especially in winter time when the water in our own natural pond is a bit cold for normal people. Polar bears, feel free.
It's just very chic at Pierre's and he is a very kind and authentic B&B keeper. The spa is only accessible by his guests and ours (and me and my friends, yes yes), so chances are that you have complete privacy.
In the weekend Pierre is too busy, but on weekdays it is also possible to book a massage with him.
Conclusion: Pierre offers everything we'd wish for to complete your stay at Le-zen. Merci mon ami!
