We stayed in the double room for 3 nights. The location is superb, just one minute from Farringdon station (train and tube) and many many nice bars and restaurants just around the corner.
The appartment is super clean (situated in a modern building) and the bed and shower are very comfortable.
Although we didn't meet Kian, we always got an answer within 30 minutes to any message and he's more than happy to provide you with any kind of information you'd like. All in all a really good place to stay compared to all the overpriced and not so nice hotels London has to offer...
