Our stay was really good. Tete and Ian were very friendly and helpful hosts. The house was clean and pretty near the the Tube station. The room was quite noisy, being on a busy main road, but we were so tired after long "tourist" days that we always slept like logs.
Although Ian and Tete live in the house they keep pretty much to their own quarters so we never got the feeling of getting under their feet or them getting under ours. Summing up - recomendable - go for it.
