Max & Billie's studio is perfectly located in Notting Hill, very close to the main attractions of the city, but in a quiet and beautiful street. They gave us very fast feedback if we needed information, and we didn't have to wait for them at the check-in since they have a smart way to collect keys. Our studio was at the third floor without elevator, it was not a problem for us but if you have any problems with stairs, ask first. It's quite difficult to find a decent accommodation with a reasonable price in London, so I would recommend this place for the price and the position.
