The flat was very spacious for the two of us - a bonus too that we didn't need to share a bathroom! We found the bed to be very comfortable and the space easy to move through. Everything was clean and there wasn't much stuff everywhere which is perfect - we could lay out our stuff very comfortably.
I also liked the building a lot, we felt very safe and secure. Lastly, the neighborhood is outstanding! Easy 10 min walk to South Kensington or to Sloane Square, lots of shopping, cafes, and restaurants. We had the best vacation!
Ari was kind about checking in before and after our arrival. He offered an early check-in without us asking and allowed us to come by even earlier to drop off our luggage! It was very, very helpful! Overall Ari responded quickly and kindly.
