We enjoyed our stay at Sarah and Gael's Airbnb in London. The apartment is close to Kings Cross station and numerous bus stops so it was easy and quick for us to go on our daytrips. Both check-in and check-out was simple.
We didn't find the oven/microwave or sofa bed instructions in the manual but have asked for this to be added. Besides those, the manual was very helpful. Also we suggested moving the bathroom light closer to the door, currently you need to go down 3 steps to reach it, which can be difficult in the dark winter mornings.
The bathroom itself is modern and clean. The kitchen has a fantastic range of spices and various cooking utensils but has no "basics" (milk, butter, bread, cereals etc). For long stays this would not be an issue with the supermarkets nearby, but it would be beneficial to have some avaliable for shorter trips to save bringing your own.
Finally, the street noise does not affect you in the main bedroom but could if you sleep on the sofa bed.
Overall, thank you for a great stay, we would happily stay in the apartment again.
