The place is very peaceful and cozy. Host Sylvan is kind and open-mind. When I asked to get some tips for travel around, she was very helpful to explain it, which introduced portobello market for weekend and the way to get downtown.
Unfortunately, first and second day wifi was broke down. Sylvan said it wasn't house wifi problem, but the town area signal problem. One more thing, the house to london downtown takes around 35-40min by bus or underground.( I didn't expect that london traffic jam is quite often and general slow system somehow.) Generally, I am very satisfied and I would like to stay here again.
