I stayed at Lesley's for about 5 days. Lesley is an absolute delight, very helpful and yet respectful of one's privacy.As a hobby musician, she does record her own vocal sessions in the room above (thin walls). I work with musicians a lot, so am used to this, but if you aren't, then keep that in mind. The apartment is very clean and comfortable. Her King Charles Spaniel Valentino's a quiet little pooch who doesn't bother anyone. There was morning coffee and breakfast accompaniments (which I availed of only one morning), but there's also some neat little breakfast cafes in the neighborhood.
The neighborhood (prettier than the photos) is beautiful and boasts of some wonderful restaurants and cafes from Turkish (must try Chambers) to Vietnamese to Indian to fish & chips. The bus stop is about a 2-minute walk from the house that'll take you to Mile End and the red line. If most of one's London itinerary is set in Zone 1, then be prepared to factor about 45 minutes to an hour to get to the heart of town.
I would highly recommend staying at Lesley's for it's a place that is comfortable, value for money and with a pleasant host. The distance is a small drawback, but when you're on holiday and have time on your hands, it isn't a huge worry.
