I recently stayed at Dmitry's place with 9 fellow mountain bikers. The house was super clean and well laid out for crowds, both indoors and outdoors. There were plenty of accommodations (dry foods, linens, laundry and dish detergent), etc. The nearby trails are also fantastic.
The house is beautiful. Upscale appliances, tilework, heated floors, etc. The hot tub and sauna were also a great.
I also found the owner to be a great communicator who handled any minor special request with ease. Stay here if you want a beautiful, clean, well-equipped home with an owner who's going to do all he can to make your stay wonderful and be out of your hair while you're relaxing. 5+ stars.
