We arrived at Aviva Studios after around 12 hours travelling, and found it very easy to reach via underground train from Heathrow, with the help of accurate directions from Boris.
Our studio was neat, nicely decorated, fresh and spotless, and was extremely well-equipped for a short stay, including plenty of the essentials in the kitchen for making breakfast and light snacks.
The area is quiet, leafy, well served by buses (we used to 27 to Paddington numerous times) as well as being a stone's throw from places to eat and shop (Tesco Express very handy at the tube station).
We slept soundly and really enjoyed our little haven in London and we found our hosts to be extremely pleasant, welcoming and helpful.
I have recommended this little gem to several of my friends, as it is very good value and we loved staying there.
