Our stay went well, the host was helpful and easy to reach, the flat located in a perfect location in central london and it fits comfortably for two guests only and not suitable for kids.
Just to be clear and to share my experience in this flat I can say that cabinets was not ready to use and many stuff are untidy, dusty surfaces and there is tiny broken glass in the bathroom.
The bed upstairs is not that comfortable as the ceiling is low and you have to bend your back.
