Perfect for our 10+ day family (4) trip.
The facility itself is a hotel, so you have no concern on security and such. Self check-in is super easy. Place is clean. Super strong shower is definitely a plus :) 30sec walk to supermarket.
South Kensington is such a lovely neighborhood. Access to tube is 8-10min walk. King’s Road is less than 10min walk. You can jog to Hyde Park. Museums, restaurants, all there.
Absolutely recommended.
