This is an excellent place to stay. My time at Michael's house was excellent. So far it's the best and cheapest place that you could find in London.
The location is not bad. The house is 15 minutes walking to the metro station and it is easy to get a bus around. You will also found restaurants, coffee shops and supermarkets close by.
Although the room is small and not super clean, it is warm and comfortable. Michael is really respectful and kind. He is very intelligent and we had good conversations.
I really felt like I was made welcome during the time I stayed there.
