It was a pleasure to stay at Katharine's place. The room is exactly as it looks on the photos - very bright, spacious, extremely cozy and clean. What we loved the most are the amenities in the room like - microwave, fridge, kettle, toaster, plates, cups even the selection of teas and soups. It felt more like a studio apartment rather than just a room. The bed was very comfy and the bed linen were of a high quality.
Katharine and John were very welcoming, helped us out with all our questions, allowed us to have a late check-out and leave our luggage until the evening. If you're looking for a great place to stay in London, I totally recommend it, great value for money!
