I have rented a private room with my friend, and the price and location were very good, close to verious shops and the Paddington station.
Our room was on the 5th floor and there wasn't an elevator available, which wasn't a dealbreaker for me, but something to bear in mind if you have mobility issues. Facilities in the room were new, shower pressure and temperature were good, but there was no extractor fan in the bathroom, so the bathroom and the room would get very steamy.
I have been unlucky and my stay happened during the heatwave in London, which made being in the room practically unbearable. It would get extremely hot, and while the hostel provided a fan, it did little to nothing. Would not recommend staying here in the summer, but I'm sure in spring/autumn it will be fine.
