Cute, clean, small flat in a good location. W Ken tube is a 3 minute walk, there's a good laundry service nearby, a good brunch restaurant, and an excellent Thai restaurant as well. Grocery stores are also within walking distance.
The flat is very clean but quite small and proved a little difficult because of the bed, which is a foldout couch. It's definitely not meant for two people, at least not two adults. If you're traveling solo and aren't very tall, then it would be perfect. That is the only thing keeping me from giving the flat 5 stars.
The host was lovely and left us some prosecco as a welcoming gift. And, after realizing that her iron was stolen/missing, she graciously paid for my dress shirt to be ironed for a fancy dinner reservation at Gordon Ramsay the night we arrived.
Overall, everything was good, but be aware that the bed, as I said before, is meant for one. If you're traveling solo or you don't mind a seriously tight squeeze with two people, then I'd recommend the flat. It's in a great location and the host is lovely.
