Agata's appartment is truly a gem! It is very nicely renovated, very tidy and clean, and tastefully furbished.
Agata requests her guests to follow quite some rules around the appartment to keep it tidy, which is great if you prefer a clean environment but might put you off otherwise.
The location in South Kensington is very nice. You are less than 5 mins walking distance from lots of shops, restaurants, and bars on Earls Court Road and from the Earls Court tube station. However, the road itself is a quieter residential road, so there is not too much noise during the night. Brompton Cemetery is also very close.
