@Cinzia-and-Poyraz0 Nah, reviews from a host don't count in Super Host status. (But I'm sure you were the epitome of the perfect guest, right? 🙂 )
How do you know that you no longer have Super Host status? The assessment period doesn't end until April 10. Did you get some kind of notification to that effect? I'm still waiting...somewhat anxiously but not really concerned as my guests don't even know what it is!
Anyway, if in fact you lost SH status, my best guess is that you didn't meet the reservation requirement of 10 reservations in the last 12 months. Is that possible?
If not, just be patient. Some of my host friends are just getting their emails about Super Host status today. Have a glass of wine and relax!
