We thoroughly enjoyed our week in Oliver's apartment. While a little bit of a hike from the Tube to the flat with luggage, the location of the apartment is quite central and it was easy to get to "downtown" by public transport and even walking. Loved the food stalls just across the street on week days and the market down Roseberry (?Exborough?) was a great place to go for a morning coffee and pastry, or an evening meal. Lots of other restaurants within a block of the flat.
The apartment is cozy, as others have written, but the space within has been used very effectively. Modern set up and everything works well. Light and airy with tall ceilings in most of the flat. Oliver's support team was highly responsive and easy to communicate with. To note - the apartment would probably not be suitable for those with mobility problems - no elevator and relatively narrow stairway to get to 1st floor flat.
Would not hesitate to stay again.
