I spent two weeks in Song Yi's home and this is definitely my best airbnb experience - it's more like a home than an Airbnb. The room is super clean (without any spots/ dirt) and warm with new carpet. The room and bathroom are modernly furnished with desk, wardrobe and a super cozy mattress and duvet.
Song Yi and her family (especially the kids) are really friendly. She treated me with delicious korean soup and snacks :))), plus provided everything I need (e.g. extra pillow, rack). The kids always say hello to me. It's truly lucky for me to stay in this friendly and clean house while I started my new job in London!
The house has proximity to supermarket like Waitrose, Lidl and Korean markets for groceries, it's also next to the high street so there are lots of restaurants to dine in ( a lot of nice Korean restaurant). Although it seems far from city center, it indeed just took 25 min train to Waterloo/ Vauxhall - which connects you to tube. I will definitely recommend it!
