Overall we enjoyed our stay. The location is fantastic, the place was very clean and the check-in process was very smooth. There were a few drawbacks to the apartment that might be a dealbreaker for some:
1) The sofa bed is extremely uncomfortable and unusable. We requested a mattress topper which was kindly and very quickly supplied by the host, which at least made it bearable for the week. But we were still left with the option of sleeping uphill or downhill. It needs to be replaced.
2) The toilet has a ridiculously weak flush, meaning it had to be flushed as many as 15 times in a row to clear contents. Not how you want to spend your time in London!
3) The gas hob only works if you hold the gas knob down while cooking - very awkward indeed!
For the above reasons, we could only recommend the apartment to a couple (not a family) who don’t plan on cooking. The location alone would make it a great choice in that case and we would certainly return if it was just the two of us.
