We visited London for the first time with family and really delighted to have a place and warmth like this.
Another best part was closeness to Station and on the main District Line where all the main stops (palace, museum, London eye etc) come by for Sight seeing. Even the hop on and hop off buses ply from Victoria which is on the same line.
Hammersmith is also close to Airport.
I would definitively recommend this place to any one coming with family (5-8 members).
