Large garden-facing double bedroom

From 1st June till September: we have a large garden room available, with double bed, table, desk and piano, in a beautiful, Georgian detached house. It is a family home, in good condition, with a large garden. The room is available while most of us are away. One family friend (female) will be living upstairs. We are looking for a responsible, independent, female, short-term lodger, who can either self-cater or share meals - to be negotiated.
