Big flat indeed, with all you need: the tube station is pretty close, a big Sainsbury's market as well; we all had towels, shampoo, conditioner, hairdryer, and many covers were available in case, but we didn't need: you can also pre-set the heather - the shower is good and the water warm; washing machine and laundry machine in the house, 2 big sofas, everything you need to make your breakfast. Small notice: it was declared "breakfast included" but it was only coffee and tea, nothing to eat - something you can easily manage by the way.
Matt and Ian have been super available for any information before and during our staying, very kind and quick in responding.
