We had a great holiday at Olivia's. The flat is nicely decorated and perfectly equipped, even the smallest item was to be found in some drawer (ice cubes! food bags!). It was very friendly and clean prepared for our arrival.
The walk from the tube station is not far and safe (don't worry about Hammersmith flyover, it is not a problem, neither in terms of noise nor safety!). Many tube lines and buses take you everywhere. There's plenty of shops around. It was nice to have access to the small garden.
The great asset is the river Thames just around the corner with all the views and pubs and the fabulous bridge and Thames path and all the historical arts-and-crafts places you can visit!
This place is perfect if you want to explore London but still have a quiet, relaxing base camp each evening. Olivia always responded quickly and took good care of us even when not at home. We definitely recommend to stay there!
