We had an absolutely lovely time in Guillaume's home. Everything was as described: four spacious bedrooms, two bathrooms and a modern kitchen. The children loved the toys, we loved the books and modern conveniences.
The house is about 10 mins walk from Peckham Rye Station. From there you can get to the city's centre in about 20 mins. Guillaume was really helpful and understanding. All in all a brilliant stay and we'll certainly come back as 5 days is not enough to scratch the surface of what London has to offer.
