It was a great stay! The flat is very nice, there is a garden, it is in a very quiet neighbourhood, near a tube station (and even nearer to the overground!). There was everything we needed, the beds were very comfortable.
We didn't get to meet our host, but one of her friends (very nice) came to give us the keys and she explained everything we needed to know. Our host was available by phone though, she seems to be very nice.
We can recommend this accommodation wholeheartedly!!
