Just stayed there for 4 nights with my family (2 adults and 2 kids). Nice, clean apartment, plenty of space. Kitchen fully equiped. Didn't discover much neighborhoud but for us was important easy access to central London. And it was. 2 minutes walk to train station, 5 minutes on the train to London Bridge (which is very nice area with shops, bars, restaurants and market) and there are two lines of underground tube.
Jaz and her husband Dominic were very welcoming, helpful hosts, so definitely would stay with them again.
