Three of us stayed at Angela's house. Everything was perfect for our short stay (4 nights): cleanliness of the apartment, small kitchenette for meals that don't require much cooking, location 5 minutes from Liverpool street as well as Bank, breathtaking view of the skyscrapers nearby and Angela's reactivity. Access by code is very convenient. The only downside: the sofa bed, uncomfortable even for a single adult.
Note, an M&S just across the street, no need to go to Broadgate to get supplies.
