1 room house of 21m² in London

Room is very large with a super king bed which can be for a couple or separated into two single beds. It’s a bright and airy room.I live in a house with a very large spare room. The bed is super king but can be made into single beds. My house is very welcoming. The bathroom is shared. Guests welcome to make light use of the kitchen and garden. I food should be eaten in the dining room. Shoes should be left in the porch.
