In summary, Fabrine's place is very comfortable, well-appointed and in a great location. It was well situated for the conference we were attending but also close to a tube station for travelling elsewhere. The accommodation is modestly sized but not small by London standards. Everything one needs for self-catering is thoughtfully provided. There's plenty of storage space. Bathroom is spacious with an easy to operate, instantly hot shower. And dinky toiletries provided!
There is even a safe in one of the cupboards. Unfortunately, we used it and then left some items there! (We're just not used to having one.) Our host very helpfully - and promptly - wrote to advise us. And then, even more helpfully, made sure the items were returned.
We highly recommend!
