5 stars for Helen. My boyfriend and I had a great time at the flat. We loved the high ceilings, floor-to-ceiling windows, well stocked kitchen (except no microwave), hot shower (but only one set of towels each) and various light fixtures on useful dimmer switches. Helen was a great host and was quick to respond to any questions, and maintenance requests.
Location was conveniently located within a 5 minute walk to St. Pancras Station which has many tube line connections. You can get anywhere in London from this flat. We also enjoyed waking up each morning to the faint, but delightful smell of the French patisserie located below the flat, and getting a breakfast pastry and cappuccino each morning for take-away. The neighborhood was safe, had a grocery store within a 5 minute walk, as well as bike rental stations.
The check-in and out process was seamless, as Helen met us on the corner to show us around the flat. There was an in-unit washer/dryer, but we did not use. The closet was an adequate size with plenty of hangers. The bathroom had lots of shelving space for toiletries. We would highly recommend this flat to those visiting!
