Everything was wonderful - the beds were super comfy, the facilities were spot on. The location of the flat was perfect - busses right outside the front door and underground literally around the corner.
The kitchen is well presented and everything required for arranging simple meals was provided.
The stairs must be mentioned - we were warned ahead of time about them and yes - they are steep and not suitable for anyone with mobility issues.
Otherwise - the ideal spot to stay when visiting London! We will definitely be back!
