The house was very pleasant to stay in. We found our stay relaxing. The place was spacious enough for 4 adults and a teenager. The kitchen was well equipped making cooking very easy. We didn't miss anything during our stay. The area was quiet at night (we slept with windows open).
The location is also very good: metro and bus were accessible nearby (2 to 15 min walk depending on the option picked). There is a co-op, a sainsbury and a tesco express within 10 minutes walks.
Finally the little touches from Diane made us feel welcome. Diane also sent a few notes upon our arrival that were very clear and helpful.
Diane was also fast to answer when we needed help. I would definitely recommend her place and if returning to London would consider staying there again.
