We spent 8 days at this flat in late April 2017 and enjoyed ourselves. It's bright and fresh as advertised...recently remodeled. The fact that it's a non-smoking, no pet unit with hot water heat radiated from the floor were all significant factors because we have problems with allergies. We also needed a king size bed. Not many units are available with all those features. The other major plus was that a Chris, the owner, was available on quick notice when we needed something.
The unit could have worked even better if the towels and sheets were washed with a non-scent soap...again, scented soaps also trigger allergies in a lot of people. We bought non-scented soap and washed the towels and sheets right away. Although the heat and hot water were great, they weren't working properly for the first day...probably because the last tenant fiddled with the boiler controls when it got too hot out. Chris fixed it pretty quickly once we understood that it was off. We also had a more spontaneous error in the system on the fourth day and the owner was out of town and not reachable. So, we spent a day unable to shower and do laundry as we had planned. Once the owner found out, we were able to reset the system with some phone instructions. It left us with the sense that the system is complex and not very robust. At the very least, we needed explicit instructions from the start.
It would have helped to have instructions on how to operate the electric stove and oven, the washing machine and dryer, the boiler, and the heating thermostats. All were modern but not intuitive...and, we're fairly tech savvy. The instructions should also include where to find the hair drier, iron and ironing board. Paper towels toilet paper and trash can liners should be provided.
Having said that, we'd be back. We thought it was good value, quiet and in a good location to see London.
