Elena is a most helpful and gracious host. The room is spacious, the bed was reasonably comfortable, spoken by a 63 year old bloke with a temperamental back.
Nice shared bathroom and shower with kitchen privileges. Since it's a shared space with host and her young son, this room is great for a quiet, conscientious person who is mindful of others and cleans up after him/herself.
Walk out the front door and you're literally steps away from restaurants, pubs, cafes, stores, 2 underground train stations (Bayswater and Queensway), and Hyde Park. It's a great neighborhood. The neighborhood can be noisy at night so bring ear plugs. This was by no means a deal breaker for me though, I'd definitely stay here again.
