Positives:
The location was central, in walking distance to the tube and many great sightseeing/or fun-to-go places such as Oxford street, Hyde park, and Bayswater (which is somewhat close to Nottinghill).
Not so positive:
Please make sure to contact host prior to the trip about exact apartment address info and how to get into the apartment (key or pin pad). Unfortunately, I did not receive all information prior to my trip (timely) and thus had to message host from nearby cafe which was stressful given a foreign country and no proper internet connection.
