We didn't really like our stay at Rich's house, but we have to admit that we didn't read the rules before booking (we only read the description and comments). Here is our feeling:
Pros:
Really clean and tidy, he puts some tea and water in our room before we arrived, which was really Nice. Thé place is quiet and Victoria Park is really Nice and close to the house.
Cons:
Thé Host is not flexible, you can't eat or have breakfast in the living room, you will have to do it in your room. You actually can do what you want as long as you are IN your room. You can't use the kitchen out of thé times hé sets in the rules (which means you can't have lunch). He basically doesn't want to see you.
If you need à place in London just to sleep this is the perfect place but if you want to feel at home we think there are better places.
