We stayed in Andrew and Martha's place for two months and everything was perfect. We didn't meet Andrew but his response to whatever we needed was always immediate and helpful. Martha, his mum, is the most discreet and lovely person! Always smiling, ready to help and make you feel welcome, she's the perfect hostess!
The room was very spacious, cutely decorated and clean. The kitchen and bathroom were also fine (well equipped, tidy and clean).
The neighborhood was excellent (classy and safe), with amazing transportation links to London center.
All in all, we had an amazing time and would definitely recommend this place.
