Our stay at Timothy's place was just wonderful! The room and the whole cottage are charming and clean (we even had dinner in the little, fairytale-like garden) and Timothy has been a great host! He was very helpful and even got up at night to let us in because our flight had been delayed... It is easy to get to the city centre from Walthamstow Central (Zone 3, takes you about 15 minutes to Victoria Station), you just have to walk for another 15-20 minutes to the station. Highly recommendable place to stay, especially for music-lovers :)
