We had a really nice stay here during our final days in London. location could not have been any better being right across the street from the Underground station. Convenient if you're flying into Heathrow (assuming no strikes). The unit is up a very very narrow staircase (almost 3 flights) so keep in mind depending on your luggage, age, and health. Pleanty of restaurants, pubs, stores, cafes all around here.
There's restaurants directly below that vent oily exhaust during the day so the room gets quite warm and stuffy. Internet was inconsistent depending on where you're sitting with frequent drops.
This is a split level unit with bathroom/ kitchen/sitting area above the bedroom/entrance.
We felt secure here but a secondary door lock would be nice. Also ceiling fans would help.
