My mother and I had a lovely stay at Alexandre's place. It was located on a quieter street but still had quick and easy access to buses, tube stations, grocery stores and restaurants.
The flat was beautifully decorated and equipped with anything you might need during your stay. The bed was very comfortable for a good nights sleep and the living room was perfectly spacious and homey.
Alexandre is easy to get ahold of and was super helpful whenever we had questions or any issues. I would recommend this flat to anyone looking for a comfortable, beautiful and secure place to stay while in London.
