I booked the apartment a few days before the check in date for a colleague of mine travelling to London for a business trip. The location is good and the room looks nice form the photo. On the day the host informed me that the room isn't available as it's not cleaned yet and didn't let me know when it will be. As there's nowhere to stay, my colleague and I had to wait outside of the building. We couldn't get hold of the host until 5pm so I had to find another place for my colleague.
