Toby was great, answering all my questions within a few hours. Check-in was exactly as described, with his housekeeper Anastasia letting me in after texting my arrival at Heathrow. Check out was easy, leaving the unit locked and keys inside. He was easy to work with throughout, responsive, and checked in to ensure my stay was going well.

As everyone has mentioned, the location in the Seven Dials area of Covent Garden is incredible with many nearby shops and restaurants as well as public transit. The unit itself is several stories above the bustle and is quiet with the bedroom tucked away from any noise. The flat was warm, clean, and comfortable. Amenities are exactly as described including the basic essentials. Since I stayed for an extended period, I dropped by a nearby Sainsbury's and Boots to pick up an additional supply of personal items.

A few items to note:
1) If you're travelling before Nov 2014, note that the Covent Garden Underground station is undergoing renovations and is exit only, so the nearest station will be Leicester Square which is a few minutes extra walk.
2) Do research the area on your own if you're not familiar with it, as the flat does not have a detailed area guide. I'm sure Toby would also be able to give advice if needed.
3) The shower setup is a bit of a tight squeeze, but perfectly serviceable.

Very much enjoyed my stay and would stay here again.
