This is a great place to stay. Especially if you want a place to sleep, maybe heat up some supper. It's spotless and very comfortable.
Location is excellent, about 3 minute walk to the junction of Kensington Church Street and High Street Kensington. Very many shops including a few 24-hour and small Sainsbury on Kensington Church Street.
The place has a good big bed, a good big walk-in shower, a microscopic "kitchen" with sink and a small hotplate, a pot, some bowls and cutlery and so on. Kettle, toaster, TV. Perfect for making a pasta or heating something up from the big Whole Foods on Ken High St. Just very little floor space. Very good towels and linen. Faultless wifi. Small TV. Mains and USB power.
It might not be obvious but the whole building is rooms: more or less a hotel without any reception or bar or restaurant.
Although they try to get you to use the app for digital keys, they will give you "physical" keys if you ask, and they put them in a lock box outside.
