The location is very good with the subway station just a three-minute walk from the apartment. Check-in was good, but unfortunately, the fire alarm was beeping every half minute when we arrived. After ca. three hours, it was solved and the battery was successfully exchanged. It also took some time to get the fridge and the stove to operate, but after some trial and error we finally managed it.
After these initial hiccups we enjoyed our stay here. It is a good basis to start from, especially for Notting Hill and everything on the Central Line.
