Great place to stay for an extended trip. We moved to the UK and needed a place for one month while we got settled. Emy's place was perfect. It's walkable to several stations (including Paddington), near the Paddington Recreation Ground and Little Venice. The extra gym room/work space out the back is what really made it though - we both needed to work in the flat at times and we could both be on calls at the same time without having to work from the bedroom - one of us at the dining table and one separately in the gym room. Having weights in the room was good for a morning workout - well-equipped setup. The place heats up nicely in the winter - we weren't cold at all.
Most of all, Emy and her husband are those type of hosts that you feel you know even though we never actually met. Amy was super responsive and nice, and one or both of them clearly loves cooking - they have a really amazing selection of spices and nice quality cooking kit in the kitchen - great for a long stay
