I have booked a holiday rental for the family in Norfolk towards end of July. We desperately need the break but I am nervous about going away as have chronic asthma - it is under control just inhalers used. The property will be cleaned well between guests they have a covid cleaning certificate, but I still am worried about things like carpets how they can clean this thoroughly with guests arriving later same day. We will arrive about 6 hours after the guests check out. Am I worrying unnecessarily? We plan to totally self cater and just enjoy the coastal walks and quieter beaches.
