i will be completely honest here.
Lily and her husband welcomed us super warmly and they described everything we need about transportation and house rules and the area. they are super helpful people.
About the location;
its not that far from city center but its not close to underground. You need to take a 13 min bus to underground and then after canada water station to city it takes around 15 to 20 mins more. So your one way journey to city center is about 30 mins with two public transportations. if you are there for few days its not really practical. we went to scotland and came back to london to stay for one more day and we've stayed in tunehotl in liverpool that time which we found much more practical. there is a tesco but its not 24hrs open and still 10 min bus ride. so far from groccery too.
about the house;
nice, secure and silent area. there is a canal for to have a romantic walk. room and towels were super clean too. well... However, shower sucks. it had water pressure problems and the hot-cold adjustment is really painful and almost impossible to adjust. its weather super hot or super cold. i dont understand how a house located in a country that has rain for 12 months a year and still having a water problems really. Even there is problem it would be wiser to invest on water pump then an internet tv which we found completely useless. we didnt even switched on the tv. after a long day of walking and exploring London, only thing you need is a nice shower and sleep tho.
to sum up;
UK is an expensive country. even public transportation has same price like taxi in my country. so i'd rather stay in city center next time.
Thank you for your hospitality and great and kind communication dear Lily. we wish you happiness.
