Aviva Studio was a very good place to stay in London. It was conveniently located just a couple minutes walk from Hammersmith station, which connects to 3 of the underground lines, making it easy to get anywhere in London. Also it is on the Picadilly line from Heathrow Airport, which makes it very easy if you are arriving there. Boris and his Wife were great hosts and the apartment was clean and well maintained.
There was slight mix up when we arrived and our room wasn't ready yet. Boris set us up in the small Hotel directly next door for our first night. It could have been a bigger inconvience then it was but Boris handled the situation quite well. This place is a great value and I would stay here again.
