I spent one month at the Diana place and my experience was absolutely positive. The room is very nice and cosy, exactly as it appears in the photos. The house is located in a very quiet area in Lewisham 3 minutes walking distance from all the principal amenities and 8 minutes distance to a big Tesco and the DLR and train station.
In the flat are living other people from all over the world and I found them being very nice and friendly, helping me with all the basic needs as I have just moved in the city.
Even if I didn't meet Diana in person, I have got a good opinion of her. When I need to contact her for some reason, she suddenly answer me and always has been very kind figuring out any problems. I am glad to have spent time there and I surely recommend this place to everyone.

Good luck!
