Since I booked the place Biba's was always responsive and alert to give indications and to accommodate to the check-in time.
The place is conveniently located. You have all the basics and more within walking distance, and the building it's within Kenington park, which gives the plus of less noise and nice views for enjoying a coffee or do some reading when you're not exploring the city. I arrived late at night almost everyday, and had no problem with public transport or safety concerns. The Oval station will give you access anywhere in London. But if you like to walk, you're not more than one hour walking from all the main locations in London.
The room was clean and comfortable, and you also get access to the full house. It was good to have the chance to cook some meals after days of traveling.
Definitely a convenient place to stay in the rather expensive London. Hope to stay again for my next visit.
