I had a lovely staying at Allan's place. The room was big enough, clean and the bed was very comfortable. The kettle inside the room with coffee/tea was a huge plus for my wife as she can not speak in the mornings without drinking a coffee first. The house is located in a quiet and lovely area. Within 4-5 min walk you have pubs, restaurants and grocery stores. There is also a nice park right across the street.
Although we did not get the chance to meet, the communication was very fast and easy, Allan giving me all the needed details for my accomodation.
One thing to take into account: if you travel during weekends have a check on-line and see if there are any tube lines or stations closed as this often happens.
