I'm disappointed. I booked a room and then canceled a few days later due to reconfinement. I canceled it 2 weeks in advance. They charged me 35 to supposedly return them to me "on my next visit to their place", without even asking my opinion. I find that unacceptable.
I also expressed my dissatisfaction by email. I haven't even received a response.
