I had an issue with the heating being on at night: there was no option to turn down radiators, yet if I opened the windows then there was too much traffic noise or sirens on the Cromwell Road for me to sleep. So maybe bring some air plugs! Otherwise, a few small issues — tricksy blinds, a weak-flushing toilet — were mitigated by lots of good things: free bananas, juice and coffee; plenty of plugs; superb wi-fi; a top kitchen; a hair-dryer; and, above all, the sheer convenience of being a literal stone's throw from a Tube station (and very close to supermarkets).
