The location is terrific, truly in the heart of Covent Garden, with dozens of shops and restaurants close at hand, walkable to Trafalgar Square, museums, etc. The unit was very clean, with a great kitchen and two bathrooms (a big plus for London AirBnB units).
The unit is on the second and third floors of a very steep walkup -- a bit of a challenge with all our bags, and if we had had limited mobility, this would have been unworkable. For travelers in the future, I recommend making it clear in the description that the unit is on two separate floors and that they are the second and third floor.
