Clean and comfortable. Host is responsive. The room was next to the train station (victoria line) which is convenient but means that it can get a bit noisy. Plus there was some construction outside during the day. The stairs leading up to the room are a bit narrow which can be a problem to some and there's no lift for accessibility.
Shared kitchen may be a bit small if two guests cooked at the same time, but I didn't encounter this problem. Really depends on the timing of each. I also liked that there are bins for recycling as well as the general bin. Would be great if there's a compost bin as well.
Overall, a nice modern flat great for a short stay!
