Pros: large space (we're two adults, two children, and had plenty of room), well appointed, nicely located in a good neighborhood. 5 minute walk to the Tube, grocery stores and restaurants. 10 minute walk to Hyde Park, Kensington, etc. Rania's a great host, was very communicative, and delivered a bag of food and treats for us, which was exceptionally thoughtful from an AirBnB host.
Neutral: apartment is on a busy street, though it's quiet when the windows are closed.
Room for improvement: master bed is a little small, wi-fi was often slow.
Overall: easy recommendation and would happily stay again.
