Edris is lovely! Everything was just as described. We felt very welcome and she and Isaac are very hospitable. We didn't spend much time in her home as our time in London was limited and we aimed to see everything that we could, so we were coming and going in the mornings and late at night. All transit is easily accessible from her house, and she hooked us up with oyster cards to fill for ourselves. The room was fitted with keys for the front door and our room, and tube maps and bus information. It is quite a trek from Heathrow, so be prepared if you have heavy luggage-- but it's possible! I had a great time.
