My friend and I stayed at Romi & Pierre's place for five nights and we would highly recommend their space to anyone coming to London. They were extremely welcoming and kind to us while we stayed there, and Romi even met us at Victoria Station to give us the keys and check-in at a time that was convenient for us. Their space is in a really secure building and is incredibly close to Acton Town tube station (5 minute walk), giving you access to the Piccadilly line which is the line for hitting many of the major tourist areas in London and for going to/from Heathrow. They were excellent with communication, both before we arrived and while we were there, and with giving advice and information about London. They even had a box of chocolates there for us when we arrived! Again, would highly recommend anyone to stay at there place while visiting London.
