Marie was very helpful. She gave me a map how to find the way from the station to the flat. She called me one week before I arrived to explain the house rules to me and how we would manage the delivery of the key.
The description of the flat was applicable: A small room, but it contains everything you need.
The flat it approximately a 7min. walk away from the tube station.
Marie took care of the cleaning of the flat: Once in a week a cleanerer came to clean the main things.
When I left the flat I just had to clean my bedding and towels, which she provided for me, and give the key to a man in a shop next to the flat.
All in all, great communication and a nice flat for a 3-weeks-stay.
