Just to clarify the kitchen/shared bathroom situation:
This is a converted house. Ground floor has bathroom off kitchen. Bathroom and kitchen are both domestic and fully equipped - kitchen has hob, oven, microwave, fridge/freezer etc. By all means bring a meal to heat up in the microwave for dinner but be warned there is no table to eat it at!
Rooms are clean, tidy and comfortable but no table in there either, and sockets (or should that be socket?) are in very poor locations so bring long cables (three metres or longer if at all possible)!
Tea and coffee is in plentiful supply. Kettle is large so allow plenty of time for it to boil. Mugs are a good size. Milk is in bottles in the fridge, not UHT, which is excellent!
Breakfast is very basic - bread, jam, oranges, apples, bananas (extremely large bananas!), yoghurts and crisps. You need to make it yourself and wash up afterwards. Washing up liquid is supplied and other equipment easy to find. There is a bread bin and a four slice toaster for the bread.
If you bring a bag, some napkins and a spoon with you, you could easily make yourself a packed lunch for the way home - jam sandwich plus fruit, yoghurt and crisps. You needn't worry about taking away from other people as there is plenty to go round.
The building and all rooms are very secure, but there is no reception so they need to arrange to let you in in advance. Check out by leaving keys on the bed and pulling the door to.
