I could not be more pleased with my experience at David and Yvette's! I stayed there for a month while relocating to London for a job for 2 years. They were very communicative before the stay, and very flexible with meeting me when I arrived (I got in 2 hours before check in time, and Yvette came home early from work to let me in!) The listing is exactly as advertised. You have a private bedroom and toilet/shower room (the bathroom is small, but you don't have to share with anyone). The best part of the listing, in my opinion, is the kitchenette! You have a sink and all the pots/dishes you could need, along with a toaster, kettle, microwave, and oven/hotplate. I used this often since I was staying for the month.
As for conveniences, the location is perfect. It is a 2 minute walk to the underground Wembley Park Station (Metropolitan and Jubilee Lines), and there is a large Asda grocery store right down the block.

Most of all, David and Yvette were very welcoming. They helped me with local advice on how to get around, sites to see, and just pointers on everyday living in London. I could not have asked for a better situation to start off my time here in London, and will always be grateful! Thank you David and Yvette - I hope we can stay in touch!
