I stayed with an older relative for 2 nights.
Pros:
1. Location (close to tube station)
2. Area (close to lots of areas, especially in West London)
Cons:
1. I stayed in the attic room and it is quite small, with a sloping ceiling. You can only stand upto full height in the centre of the room. I banged my head quite a bit the first day getting used to the ceiling. Not recommended for tall people.
2. Stairs : there are 3 steep flights of stairs to reach the attic room. Not recommended for older people/those carrying lots of luggage.
While I did have some issues with the room, it was as pictured, clean, with washer and kitchen and close to the metro station.
