Dawn and Ed are simply fantastic and their place is great. They welcomed us with warmth and were very helpful if we had any questions. The room is spotless, cute and comfy (having ones own bathroom/shower is a nice luxury!). They also had tea/coffee and breakfast basics on offer which was great.
The only thing to be aware of is that buses are your main connection anywhere, to the nearest tube or to the center, so just give yourself extra time for the unpredictability of London/buses ;)
