Me and friend stayed for one week during the IMATS and had a good time at Rajna's home. She's a very nice and warm person, who helped us in any way possible. The room was on the smaller side, but clean and tidy. Her home was around 5min away from Sheperds Bush or 10min walk to Hammersmith. The neigborhood itself was quiet and friendly. We often stayed out late for sightseeing or dinner and to be honest the neighborhood always felt safe.
I would definetely book again and recommend it to my friends :)
