I am a screenwriter working in London, a cinephile, a (lapsed) runner. My wife is American (I don't hold it against her). We have a 3 year old boy.
Please feel free to ask any questions and I'll respond as quickly as possible.
Jamie's Muswell Hill flat is a great place to stay...especially if you're traveling with a young child! Its on the ground floor, with a small garden, and is very spacious by London standards. Everything is fairly new/remodelled, and all the appliances you need are there. The neighborhood is very quiet, but you're a 10 minute walk from lots of bars and restaurants including the best fish & chips you're ever likely to order!
Jamie was very easy to deal with and I'd recommend the spot for anyone looking for a base in North London!
Jamie was great! We would love to host his stay again.
