The apartment was spacious and well kitted out; large lounge, kitchen and dining room, good size bathroom (bath and shower) and bedroom with queen sized bed, wardrobe with lots of hangers, plenty of drawer space, carpeted and fairly quiet. two sliding doors to mini balconies. wifi box in the lounge. My only niggles were with the company who offers the apartments for rent (I believe they are privately owned). We were due to check in on the Sunday, and were given a number to call 2 hours before arrival so the rep could meet us there. I dutifully tried but the number was permanently engaged. no response to my texts either. so I called the only other number I had, and after it rang out a few times I got to speak to the duty manager, who told me the number I had was for someone who wasn't working that day. she said she'd tell the person who was, and that person was waiting for us promptly at the apartment. while it worked out well, I didn't appreciate the stress of not knowing whether to travel into central London as there might be no one to let us in. If I were you, I would confirm you have the correct phone numbers the day before your stay. we got to the apartment and the cleaner let us in. she was sweet and showed us around.
during our stay we found the loo seat had come off its hinges and the water was scalding. two days later someone came and fixed it, so good service there.
all in all this was a quiet and comfortable apartment in the heart of Clerkenwell and I would stay there again.
more kitchen equipment would be good... more cooking utensils (not metal), a cafetiere, more dishwasher tablets, a new ironing board is needed, and lampshades that fit!! small things but would make a big difference.
