First and foremost Q was a great host. We were traveling with our two boys 4 and 7 and he was there at the apt when we arrived around 9 pm. Q had kept some chocolates and other knick knacks for us. he also let us keep our extra bags at the apt while we were away at cornwall which we really appreciated (we had booked the apt twice with the gap while we were away). He was also very responsive before and during our stay. The apt itself is on the lower ground flr but has good light. The living room is nice and airy with cable tv for the kids to watch cartoons when they are at home. The bedrooms at the back were smallish but acceptable for London standards (both beds are I think European queen size beds I think) so bit of a squeeze for two adults (especially if you are big and tall). Fully functional kitchen which we used for breakfast couple of time. apt is about 10 mins walk to hyde park, Kensington high street. 5 mins walk to the closest tube station. 2 mins from the natural history museum and the science museum. Harrods is about a 15 mins walk. Good option for families with a couple of kids. Neighbourhood is great and quiet.
