It was a really good experience. Liz and Paul are super nice and welcoming, and they try every moment to make you feel comfortable. The room is enough for one or two people and has a desk and a closet. They have two wonderful girls who are friendly as well. Everything is clean and you are free to make your plans and arrive at the house at any time. The house is a bit far from the center of London, but in 50 minutes you reach the center.
If you want to feel comfortable and you are looking for a clean and affordable place, I recommend this place.
