The room was mostly fine and fairly large by London standards. There is a useful fridge in the room and a well-equipped kitchen downstairs. The location is a quiet residential area. It's well-connected by public transport, although it's about a 10-15 minute walk from Queensway station on the Bakerloo line. You can get a bus more quickly by walking a few minutes towards Maida Hill - you can get a number 36 bus for example from the bus stop at Elgin Ave. to Marble Arch or Victoria station. The street layout can be a little confusing though, so make sure you have some sort of phone map available.
The main issue we had with this stay was that the host was initially not as responsive as they could be. They could greatly improve their guests' experience by more promptly providing check-in information etc.
