My wife and I rented this flat in November 2018. It was a nice little flat that made a good home away from home for the week we were there. The kitchen had all the cooking equipment we needed to make most of our meals, which saved us alot of money. Plus the price of the flat was really affordable. The living room is quite comfortable. The couch cushions flip out, making enough room for one extra adult sleeper, and maybe two extra child sleepers. The washing machine/dryer is a little small, and took a long time to dry anything, but as long as you do laundry every morning, and then set it to dry before you leave to do your tourist things, you'll be fine. Its also pretty convenient, being a short walk from the tube station, as well as several grocery stores and restaurants
The major downside for us was that it was a little noisy, especially the upstairs neighbors. We asked the owner to talk to them and she did, but they were still noisy, to the point where the owner actually had to call the cops on them because they were yelling at each other late into the night. The flat is also close to the tube, so you can hear it going by all night. This wasn't that big of a deal, but is worth being aware of.
Overall we had a really nice time and London, and the flat was very satisfactory. Jolana was a great host and I would recommend staying here for the convenience and the price.
