I stayed at Kula over the weekend of my wedding. The apartment has a great location right opposite Victoria station and the Nova complex and a short walk from Chelsea and the Kings Road.
The staff were super helpful, getting us a full length mirror specially and accommodating our request for a late check out.
My one comment would be that a little more attention to detail could improve the experience even more e.g. matching cutlery, touching up paint marks on the walls etc. The kitchen and bathrooms could also have been a bit cleaner.
However, all in all a great stay!
