I was at Alison's place for about a month. She owns a very nice and cozy house with a garden. I was mostly out, so we didn't interact a lot, but she was always very friendly and relaxed. She seems to be a very reasonable and understanding person. Even when I forgot to return one of the keys, she was really relaxed about it.
I had a lovely stay in the guest room, which is big enough for one person, bright and airy. I also had my boyfriend over a couple of times and that worked out very well. The location is good with plenty of shopping possibilities, quiet, safe, and with good transport possibilities to central London. There are nice parks around which one can enjoy when the weather is nice.
I didn't see her kids very often, as they were mostly out working, but they're are also friendly and chilled out.
Alison cooks often, so the kitchen tends to be a bit busy and messy at times, but that wasn't that big of a problem for me, as I wasn't cooking that much. The house was always clean, specially the bathroom and loo, which is quite important.
Overall, it was a very good experience and I would definitely recommend staying there.
