Overlooking Kensington Palace Gardens, The Milestone is widely considered one of London's best boutique (and thoroughly British) hotels due to the high level of service and attention it doles out to its human guests (like two staff per guest, 24-hour butler service, free internet access and even a choice of 30 bath soaps).  Pets don't go unnoticed either with the kind of VIP treatment even a royal corgi would beg for. On arrival your four-legged BFF will receive a tail-or-made welcome hamper, featuring a toy, a treat, a Milestone tag and clean-up bags. Also included is a welcome letter with information on all the hotel's special pet Concierge services like dog sitting and dog walking (bookings required 24 hours in advance) and grooming to taxi and vet services.  'At Red Carnation Hotels (RCH) we have an exceptionally strong service ethic and our ethos is 'no request too large, no detail too small' says the hotel's spokeswoman. 'This is reflected across everything and so we can arrange a birthday celebration and cake for a guest's pet or VIP - Very Important Pet, as we like to refer to them! The Milestone continues to fuss in-room (there are 44 rooms, 12 suites and six apartments, each individually designed and decorated) with custom-made Milestone Hotel pet bed, cushions and duvets; floor mats; a 'Do Not Disturb/Pet Sleeping' card;  food and water bowl (with fresh mineral water no less); Pet Menu and turndown treat.  The VIP pet offerings extend across the entire RCH group. Guests can also book an all encompassing Pampering Pet Package with inclusions such as gift baskets and grooming sessions.
