Simon and Katie were excellent hosts--from their welcome package with great dining suggestions to the fresh roses, wine and chocolates. I was visiting London for a meeting with 2 colleagues and Katie brought us an extra duvet so we could sleep separately. The meeting was at the Business Design Center, which is a pleasant 15 minute walk from their flat. I would definitely recommend contacting Simon and Katie for availability if you are attending a meeting at the Business Design Center. Their flat is tremendously comfortable, with a kitchen that invites you to cook in. With all the nearby restaurant and pub options, sadly, we only used the kitchen for morning coffee and breakfast. The dining out options, mostly their suggestions, didn't disappoint--try the Albion's Sticky Toffee Pudding. Another bonus of their flat's location is the proximity to many small parks, including Highbury Park. This area is perfectly suited for a morning run.
With out a doubt one thing that made the stay fantastic was the easy communication with Simon and Katie--they respond almost immediately. You'll enjoy interacting and meeting them, and their beautiful flat.
