It is definitely a great great great room for London travelers. I am not an English speaker so maybe my expression is not accurate enough.
1. Room is spacious, clean, and warm if you come to London not in Summer. You could watch TV with your friends or just play poker.
2. Lots of restaurants and stores surround the house so if you are hungry at night, just walk 3mins and you could get all kinds of food you want.
3. Walking 10 mins, you could arrive Greenwich Station and take southernwest line to go to center of London by another 10 mins.
4. Maz is really a nice house-owner. You could always contact him when you have any trouble and he will give you the best instruction.
