For anyone who reads this review and is thinking about staying here - just do it. It’s a really pretty unit with everything you’ll need for even week-long stays. There were no issues with things such as noise levels or temperature- London can get really cold during winter but the central heating made it feel like it was summer, it was really effective. Hot water was great too except sometimes it can come and go or take a few minutes to come but that has nothing to do with the host or the place itself, it’s to do with the building and the management.
Overall I was very pleased with this reservation and also relieved to have such a friendly and kind host - especially since it was my first time staying in an AirBnb ever.
