Fantastic! The place is basement and ground floor of a 4 floor building and includes small outdoor space at the back. It's a tree lined street, doesn't get much sunshine but that was perfect as we stayed during a heat wave so the place was the coldest place to be!
Location is one street back from the main street. Excellent location 5 mins walk from Hyde Park, two tube stations on Central / Circle line and numerous buses as well as several supermarkets, restaurants.
The apartment is very well fitted out, high quality and well maintained, like new and very clean.
It is managed by a third party company that were very responsive to any needs / questions I had.
Really enjoyed the stay and recommend it for a base to explore central London.
