Excellent transport to central London (Liverpool St St) from Clapham St (just 10m walk) or by bus (254) to Aldgate (bus stop 1 min walk). Convenient also: good coffee just around the corner. A small Tesco also.
The family is welcoming & helpful.
Safe area but, stay clear of the people sleeping rough who ask for money near Clapham Pond. That’s an issue in Hackney generally, too.
