Great location - right in between Sloane Sq and South Kensington Tube stations. Super close to Kings Rd with all the amazing shops and South Kensington with all the great museums. The front drive/garden was being renovated, but will look great when it's done. The concierge service was excellent and communication was very prompt.
We rented a 1 bedroom with fold out bed in the living room for our family of 4 (children 6 and 9) but would rent a two bedroom next time if there is availability. The one bedroom is quite small.
Apartment is very clean and has everything that you need.
