I don't do much domestic but have a couple of large mult million pound houses do one and the house is stunning but it's a nightmare booking it in,the owners are very rarely in the uk and the house can only be entered via electric gates over the years I found them to be a bit of agro.
these type of houses all ways need prior notice and if there not permenant uk residents that 2 monthly soon goes to 3 or 4 monthly.
Defiantly add rich tax
