I stayed at Alison's for over a month and the experience was really satisfying. The room is big and cozy, an ideal place where to relax at the end of the day. Breakfast are great and the kitchen is well equipped if like me you want to cook your own meals. Position is great, you are just two minutes from the Central Line and you can also reach Ealing Broadway either by train or with a nice 25 minutes walk. Neighbourhood is safe, there is a park nearby, small groceries and a pharmacy.
Last, but not least, Alison is a great host, always available and supportive. I truly reccomand also for long stays and I am sure you will find yourself at home like I did.
