The housekeeper is very nice. He helps to communicate with various things. The house is very warm, especially the bed is very comfortable. It's also very quiet and peaceful to sleep at night. The supermarket downstairs is convenient for shopping and the price is also affordable. I recommend it to other friends, and I will definitely come back next time!
