Cannot contact upcoming guest as his account is "temporarily unavailable"

Normally I would agree with you but the subject of French leaving low ratings has been discussed on here several times (hence the :wink: !).
I should have been more explicit and said low star ratings rather than crappy reviews, in hindsight. The reality is that I’ve hosted over 60 sets of French guests and around 70% of them leave 4* or less. The actual written reviews are no worse or better than anyone else’s but that percentage of 4* ratings is way above the norm. I’m a superhost at the moment so it is definitely a significant pattern with French guests. I don’t have a problem with it, it’s just an observation.
