The Aviva rooms are great, and I would recommend them for your stay in London. They are conveniently located in Zone 2 in a short walking distance to the Hammersmith tube station, and there are also several buses that stop right across the street. Also in a short walking distance from the house there is a shopping mall and shopping area as well as two traditional English pubs. It was very easy to take the Underground straight from Heathrow airport to the studio. Boris is very friendly and graciously greeted me, even when I arrived earlier than planned. The Aviva rooms are just like having your own hotel room, but without the hassle associated with low cost hotels. I originally planned to stay at a hotel in London but they were so expensive and the guest reviews were awful, so I turned to AirBNB, and I am glad I did. Aviva 7 is half the cost of comparable hotel rooms AND you get a kitchenette. If you are looking for a hotel room experience, this is the property for you. You have your own studio and can come and go as you please. I didn't see Boris during my stay, but I knew he was available on site should I ever need anything. I think you will have an enjoyable experience if you come with realistic expectations for the cost. Yes, the walls were thin, the bed was not particularly comfortable - but you would get these same conditions at a hotel room for TWICE the price. I would recommend, however, that if you like to read in bed, to bring a portable reading light as their is none in Aviva 7 (only light source is the window and overhead room light). Also if you like to sleep with two pillows, to bring a second with you (although you may be able to ask Boris for one as well). In conclusion, the Aviva studios are a bargain for their cost, and the location alone is worth it.
