The location was very convenient, about a 5-10 minute walk to the Baker Street tube station, and an easy walk to both Regent's Park and Hyde Park. Bathroom was very small but functional and perfect for our needs (see: economical). Kitchenette counter became the "getting ready" station but if you need to cook has a stovetop, cutlery, etc. The room itself is very spacious and we didn't need to unpack much but it has a large closet which some may find convenient. You can also borrow power converters for a refundable deposit (they hold 20 pounds and return it when you turn it back in, very helpful). Be advised it's stairs only, no lift.
There is a reception desk in an adjacent building and the host was standing outside to check us in, this is where you can find the converters and ask any questions during their business hours.
