London is a great city and the highlight of Mark's flat is a very nice rooftop terrace where you can view the city or watch the sun rise, which we did. The flat is well equipped and provides good access to the city. A 10 min. walk or 5 min. bus ride gets you to Warwick station where you can go anywhere through the Underground (make sure you get an Oyster card).
The suite has two bedrooms, one on each level and with its own bathroom. Mark responded quickly to question and I would recommend this as a good place to stay.
